54 REPORT OF OFFICE OF EXPERIMENT STATIONS. 



of some of the irrig^ation investigations, a study of the Itlaho cricket, 

 the rchition of the honeybees to \hk\v hlijiht. and a nuniher of other 

 lines of work. An a<rrononiist has been appointed wlio has under- 

 taken considerable cooperalive M'ork among fanners in j^rowing 

 (biruni wheat at (btl'erent aUitudes and sown at different times. He 

 is also testiuir varieties of oats and barlev and conductinj; exneri- 

 ments in breeding spring grains. (Irasses for pasturage are being 

 tested in cooperation with the Bureau ot Plant Industry of this 

 Department. The chemist has conducted investigations on the rate 

 of deterioration of manures, the commercial extraction of beeswax, 

 the digestibility of Colorado hays, and the determination of alkali. 

 The horticulturist is continuing his study on Rhizoetonia-resistant 

 varieties of potatoes in coo])eration with the Bureau of Plant Indus- 

 try and has obtained good results in ])reeding disease-resistant 

 cantaloupes. 



An important line of work recently taken up is the horse-breeding 

 experiment in cooperation with the Bureau of Animal Industry of 

 this Department, to determine whether the American trotting horse 

 can be used as foundation stock for the successful production of high- 

 grade carriage horses. Up to the present time 19 mares and 1 

 stallion have been used in this experiment. There are also coo])er- 

 ative experiments Avith horses and cattle on loco, and irrigation 

 investigations in cooperation Avith this Office. The last legislature 

 made an apj^ropriation of $5,000 annually for two years for live- 

 stock work, $1,500 for improvement of grains and grasses, and $500 

 for work with sugar beets and potatoes. The potato growers in 

 the vicinity of Greeley are aiding in the latter work, and an attempt is 

 being made to breed a Greeley potato in order to avoid the annual 

 shipj)ing in of seed. All of the plat experiments of the station are 

 to be transferred to the new 73-acre farm secured last year. The 

 staff has l)een considerably strengthened V)v the appointment of a 

 veterinarian and assistants in irrigation, horticulture, agronomv, and 

 animal husbandr}^ 



The Avork of this station in several departments is being strength- 

 ened and expanded, and in others is being conducted in an efficient 

 manner. The horse-breeding work is aided by the college, and the 

 appropriations from the State Avill materially assist in other lines. 

 The shoAving Avhich the State's representatiA'es Avere able to make in 

 the important legal controversy Avith the State of Kansas, over the 

 use of water for irrigation, is a tribute to the Avork of the station in 

 that field.
