On his arrival in Detroit, at the request of Captain E. B. Ward, he accompanied an exploring party to northern Wisconsin.

I will now describe the arrangement of the laboratory. The main building shown in the plan (Fig. 64) was about twenty-four feet square; it was divided by a partition into two rooms, A and B, of equal size, and each about eighteen feet high. At the rear of this building was a lean-to shed, C; d is an entrance to this shed from without; x, a door communicating with A; and y is the main entrance to the building. The room A was used for general analytical work, and was provided with furniture and
