"Tlic climate appears to be especially suited to the production of citrus fruits, espe- 

 cially lemons and limes, which thrive particularly well, the temperature never fall- 

 ing low enough to injure them. 



"The almost constant bright sunshine during the daytime and the dry atmosphere 

 during the winter and spring months give to early fruits and vegetables a superior 

 quality that can not be equaled under the less favorable conditions in a more moist 

 climate during the maturing period, and it also insures better shipping and keeping 

 qualities. 



'•The high prices the early products of this place command in the Eastern and West- 

 ern nnirkets and the success with which they have been grown were the leading 

 inducements that led to this bold experiment in iirigation engineering. 



"An abundant water supply is assured for all lands that may be reached from the 

 Colorado River; and in addition to this the water carries a considerable quantity of 

 fertilizing matter in solution and in suspension, the value of which, when ap^ilied 

 to land used for fruit and vegetable growing, Avill, to quite an extent, offset the 

 expenditure for piimping. 



" [Analysesof this water are given which show tliat the] fertilizing value of 2|^ acre- 

 feet water is $8.55, which is two thirds of the cost of the water at 20 cts. per miner's 

 inch. 



"In addition to the foregoing, the water carries with it a good deal of clay, which, 

 with tiie other mateiials, will gradually change the sandy mesa lands to a rich sandy 

 loam where it is used for iri-jgation. 



" [The success of these and other enterprises in the same line having] demonstrated 

 that the water of the Colorado River may be used on the high mesas as well as on 

 the lower lands, the investment of capital to reclaim a large area of territory will 

 not be difficult to secure.'" 



Irrigation experiments, J. W. Sanborn ( Utah Sta. Bui. 27, pp. 8). 



Synopsis. — The results of irrigating wheat at different dates from May 13 to August 

 3, although not conclusive, indicate that early and late irrigation increa.se the 

 yield of grain at the expense of straw. In case of oats and potatoes early irri- 

 gation (May 11 to July 25) produced a smaller yield than usual irrigation 

 (June 1 to July 7). Tests of methods of irrigation were not entirely satisfactory, 

 but the results favor Hooding and bed work irrigation. 



This is a continuation of experiments begun in 1890 and previously 

 reported in Bulletin 23 of the station (E. S. li., 5, p. 215). Compara- 

 tive tests were made in 1893 of (1) early (May 13 to June 25), late (July 

 2 to August 3), and usual (June 20 to July 25) irrigation on wheat; (2) 

 early (May 11 to July 25) and usual (June 1 to July 7) on wheat, oats 

 and potatoes; and (3) methods of irrigation. 



Early, late, and usual irrigation on wheat. — The results during 4 

 years are tabulated and show " a decided gain by early and late Water- 

 ing, and that this gain accrued to the seed more than to the stem and 

 straw. . . . The 'not watered' plats adjacent to the watered plats 

 gave but 4.5 bus. per acre, showing that the lateral flow of water under 

 ordinary irrigation amounts to practically nothing, for plats without 

 irrigation generally produce about that amount of wheat per acre." 



Early and usual irrigation on wheat, oats, and potatoes. — The yields 

 of wheat and oats in grain and straw during 4 years and of potatoes 

 during 1 year are reported. " A review of the [results] shows that 

 the early watering gave an increase of wheat and a decrease of straw.
