construction of the building no car- 

 pentry work was employed, the logs 

 being framed together with tree-nails 

 and old-fashioned wooden pins. The 

 base logs of the building are six feet 

 in diameter and 52 feet long, and 

 above them and forming the remainder 

 of the walls of the building, are the 



rough trunks, with the bark still on, 

 of trees of varying length, three feet in 

 diameter. Colonnades of immense fir 

 trees. 30 feet high and six feet in 

 diameter, support galleries over the 

 main entrance, and within fifty-two 

 columns of fir and cedar trees 40 feet 

 in length support the roof.

UTAH PROJECT UNFEASIBLE. 



At the request of citizens residing 

 on Little Cottonwood Creek, District 

 Engineer George I,. Swendsen, of 

 Utah, made an examination of a nat- 

 ural reservoir site on that stream, 

 formed by a recession of the bench on 

 either side of the creek. 



The engineer reports that the dam 

 would be about 60 feet high and 200 

 or 250 feet long on top. It would be 

 a rock fill with a tunnel 200 or 300 

 feet long, of sufficient size to carry 

 the flood waters of the stream, which 

 may amount to 600 or 800 second feet. 

 It is estimated that the dam and right 

 of way for the reservoir would cost 

 not less than $30,000, and the storage 

 capacity with a sixty-foot dam would 

 only be 500 acre-feet. 



The board of consulting engineers 

 in session at Salt Lake, recently decid- 

 ed that while the project might prove 

 feasible for a supplementary water 

 supply on very valuable lands, neither 

 the conditions nor the undertaking 

 are of such a character that the re- 

 clamation fund could be used in its 

 promotion. These recommendations 

 have been formally approved by the 

 Chief Engineer.
