IRRIGATION INVESTIGATIONS. 49 



Bulletin 86, pp. 253. — The Use of Water in Irrigation. — Report of 

 investigations made in 1899. This bulletin explains the methods in 

 use in the arid States in the distribution and use of water in irrigation. 

 It gives a large number of measurements made to determine the duty 

 of water and the losses by seepage and evaporation from canals, and 

 discusses the methods by which the water supply may be more effec- 

 tively and economically utilized in the production of crops. 



Bulletin 87, pp. Jfi. — Irrigation in New Jersey. — This bulletin gives 

 the results of a number of experiments on different kinds of small 

 fruits, melons, and vegetables during 1898 and 1899, made for the 

 purpose of determining whether irrigation during short periods of 

 drought in regions where the rainfall is usually sufficient for the maxi- 

 mum growth of crops will sufficiently increase the yield to pay for the 

 works necessary to obtain the supply of water, and reports observa- 

 tions on the construction and cost of six small irrigation plants in 

 New Jersey. 



Bulletin 90, pp. 1^8. — Irrigation in Hawaii. — Discusses the climatic, 

 soil, and other conditions as affecting irrigation in Hawaii, and gives

 ried on by the author for a number of years. 



Bulletin 92, pp. 4-8. — The Reservoir System of the Cache la Poudre

 la Poudre Valley, showing the benefits to be derived from the con- 

 struction of reservoirs for the storage of water for irrigation. 



Bulletin 96, pp. 90. — Irrigation Laws of the Northwest Territories 

 of Canada and Wyoming. — Includes texts of the irrigation laws of
