and directing the lines of futnrc experiments." The intention is to 

 use data thus collected in connection with investigations by the sta- 

 tions, '' with a view to aiding the farmers in the gradual adoption of 

 a rational system of feeding, and to point out economic methods in the 

 care and apjDlication of farm manures and tho profitable utilization 

 of waste farm products."

A STUDY or THE CORN PLANT (pp. 117-121). — The rapidW growing 

 use of corn silage is given as a reason for this preliminary report on 

 the investigations of the corn plant in progress at the Station. The 

 important problems with reference to corn for silage are stated to 

 relate to the varieties to be groyvn, the methods of planting, and the 

 13roper maturity for harvesting. The experiment rej^orted in this 

 bulletin was to answer the question, " How^ much increase is there in 

 a crop of corn intended for the silo during the later period of its 

 growth? " For this purpose the crop on a field of about 2 acres, 

 planted with Burrill and "Whitman corn, was cut in two parts, as 

 follows: Each alternate set of four rows was cut September 11 and 

 the rest Septeml)er 20. As fast as cut the corn was drawn to the 

 barn, weighed, and put into the silo. Samples from diti'erent parts 

 of the field were taken at each cutting and analyzed. The results, as 

 stated in yields per acre for the different ingredients, may be sum- 

 marized as folloAvs:
