EXPERIMENT STATION BULLETINS. 253 



nted from the necessity of keeping track of the food consumed by each 

 animal under experiment. A certain amount of meal is weighed in at 

 stated intervals and the feeder gives it to the animal according to her 

 requirements instead of by weight, at each feeding. In this way the 

 feeder will watch the animal more closely and at the same time the 

 data is secured with much less labor. While these feed boxes are an 

 experimental necessity they are not absolutely necessary for the ordi- 

 nary farmer but we would be strongly inclined to use them for the 

 herd operated on a commercial basis if an account was being kept 

 with each cow, if not thev could be fed from a car or carrier. Such an 

 arrangement of feed boxes would be in the way, only, in installing some 

 kinds of watering devices. Let it be remembered that the style of stall 

 just described was designed for 1,000 pound cows suckling their calves; 

 this plan would also answer for cows being milked. 



The gutters in most of our recently remodeled stables are about G^^ 

 inches high on the stall side, 41^ inches on the opposite side 

 and IG inches wide at the bottom, with one-half inch fall 

 from one end to the other. There is much difference of opin- 

 ion as to what the best dimensions are for gutters. We know 

 of one barn fitted with shallow gutters two feet wide, and another witli 

 gutters not more than fifteen inches wide and a foot deep arranged 

 in both cases so as to hold the manure over Sunday or during very 

 stfirmy days without cleaning. Those Avitli the dimensions heretofore 

 given are furnishing very satisfactory results. One mistake universally 

 made is that of giving gutters too much fall from one end to the other 

 in order to flush them out. When this is done the urine all runs to one 

 end and the absorbant used in the gutter is not efficient throughout 

 its entire length. We have not given more than one-half inch fall to 

 the gutters thirty-five feet long in the grade beef herd barn. 



STALLS FOR DAIRY COWS. 



Figure 33 No. 2 represents stall and manger fixtures devised especially 

 for the use of dairy cows and so far as the partition and 

 chain fastener at the rear are concerned they resemble the Bidwell 

 type of stall. In this case, the stalls are constructed on a raised cement 

 platform the same as described in Fig. 33 No. (1). The cow is not fastened 

 at the head or neck, but is confined in the stall, loose, by a chain behind. 



The manger bottoms are raised four inches above the floor resting 

 on the 4x4's used for bed pieces for the partitions. The mangers are 

 16 inches wide, inside, on the bottom with back side 9 inches high 

 and sloping somewhat toward the stall with 2x2 inch strip along inside 

 at top to prevent waste of feed; the front part of manger is constructed 

 according to description given in (1) Fig. 33. Owing to the fact that 

 the animals confined in these stalls are not tied the partitions were 

 made 4 feet 4 inches high, four inches higher than for the ones already 

 described. 



There are two special features about this stall, one is the iron 

 pipe shown at P, in the illustration, which runs tlirough all the stall
