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 movements. (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, which, 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 pounds and stored in the bins provided for that purpose. 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 necessary 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 |
