Show . TKe Survey of the Lake. A tew days ago, most of the profes sional assistants of the expedition of 1877 under Lieut. Wheeler returned to Waeh'iDgton to report upon tbe work of the seaeon, A special party, having its head quarters at the observatory obser-vatory of the survey, at Ogden, Utah, will continue to proaocute during the winter, and until the resumption of mountain work in the spring, a speoial survey of much interest. This sptcial work embraces an accurate meander ol the shore and all the islands of Great Salt Lake; a measurement measure-ment cf the volume and consideration conside-ration of the -character of all the streams entering this laud-locked reservoir, aud surroundings and other measurements necessary to determine the volume of this interesting inland or dead sea. Observations will also be made to- ascertain the actual amount of evaporation from the sur-lace sur-lace with which the amount of the iutiuw can be compared and the circumstances of the rise and fall of the lake made known. - In connection, con-nection, observations with the conditions con-ditions of rainfall and other meteorological meteor-ological phenomena will be made, as time permits, at typical points along tho drainage lines. The knowl edge derived by these observation! and operations will enable Lieutenant Wheeler to produce a special physios 1 map whioh will show tne relations of the entire drainage-basin. During the Bummer mouths the Ogden observatory ob-servatory becomes the connecting station sta-tion for observations from parties of the survey at distant points engaged in the determination of tbe astronomical astronom-ical co-ordinates of a number of main stations. As soon aa the observatory is fully equipped, a series uf astronomical, astronom-ical, - magnetio, and meteorological observations will be made with a view to certain results. The outgrowth ot the most interesting examinations between be-tween the maxima and the minima of the humid changes, and, if observations obser-vations are continued for a sufficient length of lime, the law governing the secular variation iu this reipect in this aud other interesting and similarly simi-larly exceptional regions may be dis covered. This special survey is of great importance, and its inception and prosecution are due to Lieutenant Wheeler. |
