AGRICULTURAL EXPERIMENT STATION. 23 



the purpose of weighing experimental animals. It is also supplied 

 with running water (4). The stalls are built of birch and are so 

 constructed as to give the animal the utmost ease in its move- 

 ments. (See cut.) The manure drops through trap doors into the 

 basement. 



(5) Horse stalls to accommodate the horses of such station 

 officers as live at a distance from the College buildings. 



(6) The silo in the northeast corner which extends from the 

 floor of the basement to the second floor above. 



(7) Space for the storage of implements. 



(8) A room for the storage of fertilizers, grains, etc. 



(9) Small bins into which the hay rations of experimental 

 animals are weighed. 



(10) The grain room, equipped with a number of grain bins 

 and scales for the weighing of rations. 



(11) A room devoted to digestion experiments. 



The walls of these various rooms as well as the partitions 

 between them and the feeding floor consist of spruce sheathing. 

 The use of the second floor has already been stated. The hay or 

 grain is taken from the load (which is driven into the end of the 

 barn that is not floored over) by a fork, winch, running on a track 

 near the ridgepole of the barn, distributes the hay to any desired 

 point. 



Feeding Experiments with Cows and Other Bovines. 



These experiments usually involve both the feeding of a fodder 

 and a grain ration. The fodder, if hay, is generally weighed out in 

 lots of fifty poundsvand stored in the bins provided for that pur- 

 pose. Each bin is set'aside to the use of a certain animal, and a 

 cow, for instance, is fed from her particular bin until it is neces- 

 sary to weigh out a new portion of hay. By adopting this method 

 it is possible to avoid such numerous weighings as would be 

 required if the fodder was weighed each time the animal is fed. 

 In the grain room are found boxes which are marked with either 

 the numbers or names of the animals, into which each portion of 

 grain is weighed. When this grain is fed it is turned into the 

 stalls, the bottoms of which are so constructed that there is no 

 waste. Generally the rations, both of fodder and grain, are 

 entirely consumed, but if such is not the case, the uneaten portions 

 are saved and weighed, so that it is possible to calculate the 

 amounts actually eaten. If the experiment is with growing ani-
