216 SUMMAEY OF THE WORK. 



sons the appearance of rising smoke and steam from a manufac- 

 turing hamlet. A limestone quarry is located here. The water on 

 the west side of the lake is bold, and much of the way a towline 

 might be used to propel boats. The Jordan is too crooked and 

 shallow in places for boating. A magnificent water-power exists 

 at the canon, very accessible for teams ; and here the river could 

 be led out along the western or eastern base of the hills, for either 

 manufacturing or irrigating purposes." 



The following summary exhibits the amoui^ of work done in 

 prosecuting this examination: 



1. The selection and measurement of a base line, six miles in 



length. 



2. The erection of twenty-four principal triangulation stations, the 



lumber for many of which was hauled a distance of upward of 

 thirty miles. Many of these, put up in the fall of 1849, had 

 to be renewed in the summer of 1850, having been torn down 

 and used for fuel by the Indians during the winter, as well as 

 by some of the inhabitants, who probably supposed they had 

 already fulfilled the purpose for which they were erected.

3. The survey of the Great Salt Lake, the shore line 



of which, exclusive of ofi"sets, extends to 291 



4. The survey of the islands in the lake 96 



5. The survey of Utah lake 76 



6. The survey of the River Jordan connecting the two 



lakes and some tributaries 50

7. The observations from difi'erent triangular stations, extending 



from the northern extremity of the Salt Lake to the southern 

 boundary of the valley of Lake Utah, comprising an area of 

 more than five thousand square miles, and involving the neces- 

 sity of traversing a large extent of country, both by land and 

 by water. 



The triangulation of the valley south of the Salt Lake and the 

 observations for the azimuth of the base line were finished on the 

 12th of August, and the time until the 28th busily occupied in 

 preparations for our return.
