 ha\(' roiiiied to coiitioi the distiilmtion of their water supplies. These 

 societies iiavc \erv hir«>ely done away witli the friction and controversy 

 between nei<^lil)ois and neiohhorlioods so oonnnon in this country. 

 The (TO\ei"nni(>nt exercises ahsohite control over stivains and leases 

 water instead of allowing" the securin«( of perpetual rij^'hts like those 

 in (HI I- Western Suites. The report also descril)es many of the irrijjfa- 

 tion works seen and the measuring devices examined. 



Irrigation in the Valley of Lost River, Idalio. Hy A. E. Wright. 

 This r(>i)()rt deals with the peculiarities in the How of Lost River and 

 their iidluence upon the distribution of th(^ wat(>r from the stream. 

 The water of the river sinks and r(nn)]iears helow in tlu^ form of springs. 

 This sinking makes it ditHcult to know the inlluence of diversions a})ove 

 the sink on the How of the river below, and therefore complicates 

 the work of the watermaster charged with the di\ision of the water. 

 Mr. ^^'rig•llt m(>asured the stream at various points along 55 miles of 

 its course, and the diversion from the same section, to determine where 

 the water sinks and where it returns to the bed of the stream. These 

 measurements will suggest to ditch owners how to locate their ditches 

 to secure the largest supply from the stream. 



C/urrent Wheels. This report is a comi)ilation of descriptions of 

 wheels for raising water sent in by all the agents of the irrigation 

 investigations. It gives drawings, half-tones, and detailed descrip- 

 tions of a large number of wheels, with statements of the areas watered 

 and the cost of construction.
