Advantage was taken of the confinement of the party to winter - quartets to observe for t^ e latitude, to arrange and plot the notes of the survey as* far as it had advanced, and to collect and pre- • pare specimens of the zoology of the valley., These specimens have since been classified and. arranged with . characteristic ability by Professor Spencer F. Baird, of the Smithsonian Institution, - whose report on that^ sulgect is hereto appended. Specimens of the different thermal waters, also, were collected^ atid brought safely as fa? as Pittsburgh; btft, in their transportatioA thence by the express' line, most of. the vessels containing them w* re unfortunately broke?, and their contents lo$ t# This. wa* a- subject ' of much regret, as interesting results had been anticipated from the analysis. Such As escaped destruction have been carefully . analyzed by Dr. L. D. Gale, of Washington,, cpid the results will be found in Appepdi^ J\ During . the winter, a large boat was built for , the purvey <> f the Salt Lake. . This WM an achievement of no little difficulty, . ' • as almost every stick or timber used in the construction had to , be procured from the oafious of the mountains, piece by pieces and . the planking, although of the best material the country afforded, was so " shaky" and liable te split And crack, that, it was totally unfit for the purpose.. Had time permitted, it had been my pur-' pose to procure, before setting out, a couple of Francis's metallic life- boats for this service, which would have saved ipuch time and labour. The experience. of the exploring, expedition to . the Dead Sea. has fully proved the entire fitness of these boats for service. of this nature; and the ease with which they can be transported in sections, and be puf^ together for instant use, will doubtless, ten-. der them hereafter an indispensable part of the equipment for ev6ry exploration of a similar character. Wherelhe Use- of wagons is practicable, these boats can readily be mounted on wheels and jnade to answer the purposes of a wagon- box; and where this is- * ot the case, their arrangement into sections will allow of their being, packed and transported on the backs of mules with but little inconvenience. , ' |
