    Part 2:



The First House

This building was a New England-type saltbox house, the frame and lean-to part constructed in the fall of 1836 when the Whitmans first arrived. The house was thirty-six feet long by thirty feet wide and was a story and a half high, the front or main section of adobe bricks made from the dirt excavated from the cellar, and the lean-to at the rear of split logs set in grooved posts. The lean-to, about twelve feet wide, ran the full length of the house. It was divided into three sections by cross partitions, the central section being the kitchen, with a bedroom on one side and a pantry and a bedroom on the other. A large adobe fireplace and chimney ran up the outer (west) wall of the kitchen. There seem to have been two rooms in the front part of the house and a small chamber in, the upper half story, which later served for storage. The floors, doors, and possibly the partition walls were of hand-sawed boards. The roof was five or six inches of mud over a layer of straw.

Our initial problem was to locate the structure, as there was neither a noticeable mound nor a cellar depression to indicate its whereabouts. Historical information was also inconclusive. We tested the most likely areas with a soil auger and soon encountered telltale reddish-orange earth at depths from eighteen inches to two feet. This we ascertained to be some of the adobe burned by the fire which destroyed the house. A trench run through the area confirmed the fact that this was the ruin. Nevertheless, we had yet to locate the walls. We were dubious at first as to whether the adobe brick in the walls would preserve its identity. We feared it would fuse with surrounding soil into an amorphous mass, making recognition of the wall lines very difficult. By careful stripping, however, the wall lines were revealed as well as many individual bricks which had fallen to the side. In some cases we were aided by the fact that orange colored particles of burned adobe had, when the walls were yet standing, sloughed off the upper walls and fallen so as to outline the lower walls which still remain.

The ground level during mission times was approximately fourteen inches below the present surface of the ground. The walls were somewhat higher than the adobe brick rubble in the cellar itself, indicating that for some years after the upper walls fell in there had been a mound with a depression in the center. Bones of cattle, horses and other animals lay on this old mound surface along with fragments of glass, kiln-fired brick, and coal belonging to a more modern period-probably 1860 to 1870. The upper walls, of which only a few inches remain, are fourteen inches wide and were constructed by laying two seven by five by ten inch bricks side by side. Below is a foundation wall twenty inches wide. Since the distance from the center of the south wall to the center of the north wall is thirty-six feet, the length given in mission letters for the frame, the frame must have been buried within the walls. This was a common method of adobe construction. 9 The excavation has not proceeded sufficiently to determine whether or not posts went up through the adobe foundation from the cellar floor, though this seems likely as a 3-inch-diameter post hole occurs in the northeast corner of the foundation wall. Since from letters we know that the house was thirty feet wide, the post supports at the rear (west side) must have extended three feet beyond the cellar opening. We found no trace of these posts, possibly because they had rested on the ground surface and so left no holes to indicate their former location.

In June of 1947 we commenced to excavate the cellar, having by this time a fairly large crew of workmen. The cellar was found to extend under the whole house, though it was shallow under the lean-to part. The adobe-brick foundation goes to the cellar floor, giving the front and sides of the cellar the adobe-brick lining mentioned by Dr. Whitman in his letter of March 12, 1838.10 This foundation wall is four and one-half feet high and is still in fair condition though it has been damaged in two places by intrusive pits. On the west side of the cellar, eight feet in from the north wall, is a depression eighteen inches wide extending two and one-half feet west of the cellar proper. This may be part of the outside entranceway. Salt-box houses commonly had such outside entrances to cellars.

By studying the various layers which made up the cellar fill one can gain some insight into the history of the ruin. Starting at the cellar floor, squash seeds (no doubt the remains of food stored there before the massacre), a pitch pine log, several badly rotted timbers (probably cottonwood), cut and handmade nails, and a few other artifacts were found, most of them on the floor itself. These things were probably in the house when it burned and were covered when the heavy dirt roof fell. Surprisingly there was no ash and charcoal layer on the cellar floor as one would expect when the wooden interior of the house burned. It may be that the wooden interior was only partly consumed, the fire having been smothered by the falling dirt roof. Above the cellar floor is a nearly sterile layer of dark brown soil containing only a few bits of burned adobe and brick fragments, its surface considerably packed. This layer is probably composed at least partially of dirt from the roof. The packed surface represents an "occupation floor" resulting from the walking back and forth of Indians who camped in the cellar. On it were several hearths, the main hearth containing ashes over twelve inches deep as well as numerous cultural remains. On this floor were trade beads, bone fragments-of deer, cattle and other animals with the long bones broken for the marrow-, a stone pestle, net shuttles, a carved bone handle of a knife(?), stone scrapers and knives as well as gun flints, china sherds and other items of European manufacture which the Indians must have obtained from the missionaries or the fur traders. The most common item by far, especially in the ashes of the hearths, were handmade and cut nails. Evidently the Indians had used half-burned boards containing nails from the house-the flooring, etc.-for their campfires.

The adobe walls and chimney must have stood some years after the house burned. During that time, no doubt, the cellar made an excellent place to camp. Being on the bank of the river it was convenient for fishing, drinking water, and sweat baths. A sweat-house site found fifty-seven feet to the southwest could well have been used during this period. 11 The cellar could have been camped in sporadically from 1849 or 1850 until Brooks, Bumford, and Noble (cattlemen) settled on the mission grounds about 1852. All these walls and the chimney must have fallen in or been pushed over within a year or two after the Indians stopped using it for a camping place, for they lie directly over the Indian floor and hearths. This could be an argument for the contention that the walls were pushed over purposely, as by the Indians in 1855. The fallen walls created a layer of adobe brick rubble two feet or so thick. Most of the bricks were unburned or blackened only on one face. Others had been turned a. deep reddish orange by the 1848 fire. Most were broken in halves or smaller probably the result of the wall falling in while the bricks were damp. Although having been in the sub-irrigated. ground for 100 years, the bricks when taken out and dried turned quite hard, apparently becoming as strong as ever.

Large fragments of the fallen adobe chimney lay in the west half of the cellar. Though it was impossible to recognize individual bricks in the chimney, it was made of yellow adobe earth so that its fragments were quite distinct from the surrounding brownish soil. Many of the fragments were two feet or more in diameter and were deeply burned on one surface. One in particular was lying burned side down and when turned over exhibited a soot-covered surface and a half-inch deep groove along one edge. Apparently it had come from the back of the fireplace or chimney flue. There was no sign of the chimney foundation on the cellar floor or on the old ground surface west of the cellar, though the latter position is the probable one.

The cellar has yet to be completely excavated, a task that should be finished in 1948. We are especially planning to search for additional post holes in the adobe walls. Apparently the post holes here. have become somewhat obliterated by cattle and other traffic which tramped the ruin before it was covered over by flood deposit. On finding these we will know much more about the framing of the upper part of the house.

The Mission House

Mission life was centered in this large "T" shaped building, which served as a combination dwelling, school, and church. Its construction was begun in 1838, after the first house was found to be not only too small but hazardously near the river and subject to flooding. By 1840 the new house was enough completed, for the Whitmans to move into. Being very proud of her new home, which had been nicely finished inside by an expert carpenter-Asahel Munger-Mrs. Whitman sent a drawing of the groundplan made by Munger to her parents in New York.12 Thus we have a more accurate knowledge of the construction of this building than of any of the others at the Mission.

When searching for its walls we discovered a series of packed levels-occupation floors-and thin ash layers in an area that subsequently proved to be five to twenty feet south of the actual ruin. The four packed occupation floors encountered correspond rather closely to the four successive houses that have occupied the site since 1838. Level 4 represents the ground level in mission times. It is extremely compacted. Over it is a thin layer of grey ash, probably from the burning of the mission house. Over this is a fill layer of burned earth deposit which very likely came from the Eells cellar which was dug through the ruin about 1859. On this level (floor 3), which shows some packing, is a second ash layer containing material from the Eells cabin which burned in 1872. There are large quantities of melted window glass, some of it thick and some thin. Apparently Cushing Eells used thin Hudson's Bay Company type glass in his windows as well as some of the thicker, more modern type glass. In the ashes, too, were several door locks, portions of his stove, an ox shoe, powder horn, and numerous other items. He used kiln-fired brick in his chimney, no doubt some of the first made in the region. These vary from an inch to two inches in thickness and are from three and one-half to four inches wide. Chinaware on floor 3 should be for the most part that used by the Eells household, though as yet not enough has been obtained to enable a thorough analysis. Some of the sandstone footings which had supported the Eells cabin were still in place though badly fractured by heat.

Above floor 3 was two to four inches of burned-earth fill, doubtless spread about by Charles Moore after 1872 when he redug the cellar and built a frame house on the site. The floor 2 level which topped this fill probably dates from about 1873 to 1912. Except for a preponderance of square "cut" nails and other late nineteenth century artifacts the content on floor 2 was much the same as that on floor 1. On both floors the prevalent types of pottery was plain white Ironstone ware, which the Meakin Brothers and others in England turned out in quantities during the late nineteenth and early twentieth centuries. Floor I resulted when Marion Swegle enlarged the old cellar and moved most of the Moore house from the site in 1912, building a sixteen-room house in its place. The importance of these occupation floors is that they enable us to date the types of artifacts found on each. For instance, we should be able, eventually, to distinguish the pottery of the Eells period from that of the mission period.

The rear walls of the mission house were first to be uncovered. Having Munger's ground plan to work from, as soon as we found a corner and determined the orientation of the walls, location of remaining corners was fairly simple. Since the mission house was on relatively high ground there was less flood deposition over its walls, which were in places less than six inches below the ground surface. The building had apparently been laid out with a compass, for it was oriented approximately with magnetic north. Except for length the dimensions check fairly well with those given in Munger's sketch, though room "A" at the south end of the "T" front was never constructed. The building was sixty feet ten inches across the front, which was nineteen feet three inches wide. The stem of the "T" was twenty-two feet wide, but apparently the Whitmans had added more rooms than originally intended, for instead of being seventy feet long the stem was eighty feet long. Counting a small "T" at the rear (the privy), the total length of the building was one hundred eight feet. With three exceptions the adobe walls were eighteen inches thick. The twenty-inch thickness of the west wall may be due to its being worn down to the foundation which was thicker than the upper wall. The rear (east) wall was only nine inches thick and that of the privy twelve inches. Corner posts had been located in the extreme southwest and southeast corners, just inside the walls. These probably gave added support to the floor sills. It is likely that subsequent excavation will reveal such post holes in all inside corners. Though there is some indication that a frame was buried within the adobe walls, excavation is not far enough advanced to allow a description at this time. In fact, the major part of the excavation has yet to be carried on in this ruin-only the tops of the walls having been exposed at various points. Work so far done on this ruin indicates that it will be the richest in cultural material.

Blacksmith Shop

(Web editor's note by C. Boehle - Garth likely found the Blacksmith Shop corral, instead of the actual Blacksmith Shop. In the 1960's, archaeologist Paul Schumaker again searched for the site and found what is believed to be the correct location of the Blacksmith Shop).

Historical information on the blacksmith shop is extremely meager. Even the nature of the building material used was doubtful, although the fact that it was built in December and January, 1841-42, led us to surmise that it must have been of wood rather than adobe. Most drawings of the mission site, as well as most descriptions, put the shop between the mission house and the mansion house. We concentrated our efforts in that area and soon encountered a long ridge of burned earth deposit containing typical artifacts such as sherds, thin window glass, and bone buttons. Though at first we thought it might be an adobe wall, it turned out to border both sides of an old irrigation ditch which we later learned had carried water to stock corralled in this area. M. W. Swegle, farmer and former owner of the land, had moved dirt from the mansion house ruin (100 feet to the east) and used it to build up the banks of the ditch. Near one end of the ditch, however, we located a large bed of mixed charcoal and dirt that in places reached a thickness of ten inches. Some of the charcoal fragments were three inches across though most were smaller. In a few instances we encountered sections of small logs, the largest being nineteen inches long by five inches in diameter. Most, however, were three inches or less in diameter, obviously the remains of burned poles or branches of about this size. The charcoal bed assumed the shape of a large hexagon about thirty-five feet across the front or west side and thirty-two feet from east to west, which subsequently proved to be the shape and dimensions of the shop, slightly enlarged and irregular in outline.

Three levels were recognized, disregarding the overburden of mansion house fill which covered a small area at the northwest corner of the blacksmith shop ruin. The artifact content from floor 1 to 2 was essentially modern. In the charcoal bearing stratum-from floor 2 to 3 - the artifact content was meager but of more genuine antiquity. Floor 3 exhibited packing only along the east quarter of the ruin. This was unexpected, for undoubtedly the shop had a dirt floor which must have been subject to considerable packing during the six years in which the shop was used. In most of the shop the charcoal stratum rested on a soft and extremely uneven layer. This with the dearth of artifacts led to the conclusion that the soldiers who came in 1848 and stayed seven months must have dug through the ruin in search of scrap iron, a very valuable commodity in that day. It is almost certain that they took the anvil and some other tools. 13 Their digging may account for the fact that more charred timbers were not preserved nearly intact, but were broken up into small pieces and scattered throughout a ten-inch layer of soil. Undoubtedly the structure supported a dirt roof as did all the other mission buildings except, perhaps, the grist mill. It was this dirt roof which fell and smothered the fire so that much of the wood turned to charcoal rather than ash.

At the floor 3 level and in some cases as much as six inches above numerous post holes were found. The fire which destroyed the structure had consumed the posts, even eating out below the ground level, so that the post holes were filled with a mixture of charcoal, ash and dirt which preserved the squared outlines of the posts and made the holes easily recognized. A line of squared posts placed five to eight feet apart ran around the circumference of the building making it apparent that Whitman had employed the fur-trade type of construction of grooved posts between which were inserted horizontal poles and split logs tenoned at the ends. These horizontal filling pieces were in this case three to five inches in diameter, mostly cottonwood from along the nearby stream. It will be noted that this was the same type of construction as that employed in the lean-to of the first house, except that the lean-to had a plank floor while the ground served as a floor in the shop. Along the southeast side of the shop the post holes were double. The poles which formed the sides of the building must have been placed between the double posts, so that grooving the posts was unnecessary. Rail fences built in this manner are often seen even today. The inside post may have functioned for the attachment of shelves or some similar purpose. Most of the posts were ten or eleven inches wide and extended fifteen to eighteen inches below floor 3 level.

On the west side hinging off the northwest corner post there was probably a door, large enough to admit a wagon. Several of the sketches of the mission show such a door. In the southwest quarter of the ruin three eight-inch-square post holes are all that remains of the forge. The posts which stood here were probably about waist high and were boarded up between to make a triangular-shaped box, six feet four inches long by two feet wide. This was filled with dirt, forming a platform on which the forge fire was built.

The building was in the shape of a rough half circle. The dimensions from east to west were approximately twenty-six feet and from north to south thirty-two and one-half feet. The type of construction used required few or no nails and, very few have been found in the ruin. Also window glass is lacking except on floor 2 and above, making it unlikely that the buildIng possessed glassed windows. If windows existed they were probably closed by solid shutters. Window glass, a valuable item in mission times, was probably reserved for dwellings. There was no sign of an adobe chimney, and the shop may have lacked a chimney of any sort-the smoke being allowed to escape. through a hole in the dirt roof.

11 Fourteen inches below the surface there were indications of a shallow pit about eighteen inches in diameter and containing ten rounded stones, all less than six inches in length. Some were fractured as if by being cooled rapidly when water was dashed over them to make steam. No doubt this is where a Plains-type sweatlodge was located. The local type was dome shaped and about six feet in diameter made of bent branches covered by grass and earth or matting. The old river channel was about twenty feet away.

13 To encourage settlement of the Walla Walla valley Captain Thompson of the Volunteers had an article placed in the Oregon Spectator, July 13, 1848, to the effect that there were then in the Walla Walla area gristmills and sawmills, blacksmith's anvils and bellows, tools and irons, plows, harrows, hoes, etc. See F. F. Victor, Early Indian Wars of Oregon (Salem, Ore., 1894), 226. No doubt most of the items mentioned belonged to the Whitman mission.
