and irrigation engineering, and botany and horticulture. Previous 

 reports of work in similar lines may be found in the Annual Reports of 

 the station for 1888 and 1889 (see Experiment Station Bulletin No. 2, 

 part I, p. 27, and Experiment Station Record, vol. ii, p. 392). 



Report of agricultural section, R. H. McDowell, B. S. 

 (pp. 14-24).— Tabulated data aud brief notes are given for 12 varieties 

 of oats, 12 of barley, 21 of wheat, 17 of sorghum, 3 of millet, and 32 of 

 foreign wheat. There are also notes on tests for soil variations with 

 corn and wheat and on experiments with millo maize, vetches, lupines, 

 Russian sunflowers, lentils, Aztec coffee, cowpeas, flax, grasses, clovers, 

 and other forage plants. . 



Report of chemical section, D. O'Brine, D. Sc. (pp. 25-28). — 

 The results of a large share of the work of this section were published 

 in Bulletins Nos. 10, 11, and 12, of the station (see Experiment Station 

 Record, vol. ii, pp. 11, 99, 319). Two hundred and seveuty-nine anal- 

 yses were made during the year, including sugar beets, irrigation 

 waters, grasses, loco weed, larkspur, etc. Forty-two samples of rain 

 and snow were analyzed with reference to nitrates and ammonia. 



Report of section of botany and horticulture, C. S. Cran- 

 DALL, M. S. (pp. 29-54). — This includes tabulated data and brief notes 

 for 26 varieties of strawberries, 6 of blackberries, 6 of raspberries, 87 

 of grapes, 40 of potatoes, 40 of tomatoes (28 of which have been pre- 

 viously reported), 43 of peas, 9 of peppers, 6 of cucumbers, 8 of cab- 

 bages, 3 of onions, and 6 of sugar beets. One hun<lred and seventy 

 species of weeds bave been observed in the locality of the station, of 

 which 42 " are very abundant and very persistent in cultivated ground." 



Report on apiary, C. M. Brose (pp. 55, 50). — A brief account is 

 given of an experiment in growing the Chai)man honey plant {Echinops 

 sjiluvrocephalus). The station owns 31 colonies of bees. 



Report of section of meteorology and irrigation engi- 

 neering, L. G. Carpenter, M. S. (pp. 57-155). — This contains articles 

 ou water supply, irrigation statistics of 1890, irrigation literature, mete- 

 orological observations, and observations of soil temperatures. 



Water su2)ply. — The water supply of 1890, while in some respects bet- 

 ter than in previous years, was still insuflicient for the purpose of irri- 

 gation. A table is given showing the maximum flow of nine streams 

 in the State in 1888 and 1890. The discharge of the Cache a la Pondre 

 River is tabulated for each day from November 1, 1889. to Novembers, 

 1890, inclusive. The total flow of this stream for the 12 months is cal- 

 culated to have been 248,193 acre-feet. 



This is enough to cover 248,193 acres 1 foot deep ; or this amount would be enough 

 to cover 386 square miles 1 foot deep. As the area of the watershed of the Pondre 

 above the measuring weir is 1,006 square miles, this is equal to a run-off of a sheet 

 of water 4J inches deep over the wliole area. • • • Taking tho basin as a whole, 

 the average precipitation above the point where the gauging station is placed may 

 bo fairly estimated at 14 inches. This being true, the total run-off equals one third 

 of tho precipitation.
