A detailed tabulation of this work by departments follows. In 
many cases the departmental work is simply the furnishing of labor ; 
in some cases, it consists in furnishing mechanical help; and in many 
cases in actual construction. During the past four years the Col¬ 
lege Farm force has constructed over 400 feet of concrete ditch 
flume, part of it submerged with drops and approaches; it has 
built twenty-two concrete weirs on the various college farms; it 
has built some 700 feet of concrete curbing; built a half mile of ex¬ 
perimental road upon the College campus; has laid some 600 linear 
feet of concrete sidewalk; has built and completely installed an ele¬ 
vator in the college granaries; has built three complete concrete 
silos; and has done all the construction work upon a number of 
sheds, yards and buildings of the Animal Husbandry Department; 
has done the grading and campus improvement work for three new 
buildings constructed; has put in new concrete floors in five differ¬ 
ent localities used for classroom purposes; has built complete con¬ 
crete foundations for the new Soils Laboratory. The general up¬ 
keep of the grounds, campus, roads and drives has all been done by 
this same labor force. This will give an indication of the type and 
variety of service rendered aside from the strict operations of the 
College Farm. 
In tabular form this work is outlined below for each of the 
departments. The number of man hours, the receipts which rep¬ 
resent what the department paid the farm service, and the actual 
cost to the farm are indicated in separate columns in each case. The 
character of the work is not given in this tabulation, since, if given 
in detail, it would represent a mass of material of little interest, yet 
so voluminous that its publication is scarcely warranted. 
The total number of hours for each department, in man labor, 
and the total number of hours in horse labor are separately given in 
Tables Nos. 63 to 105. The data are so arranged as to show for 
each year the total number of man hours, the farm receipts and the 
actual cost to the farm. The same information is given in regard 
to the horse hours. The purpose in separating the man and horse 
hours is to show which has given the profit to the farm service, and 
which a loss during each season. 
AGRONOMY DEPARTMENT. 
The services performed for the Agronomy Department con¬ 
sisted in drayage, hauling and preparation of soils and grains for
