AGRICULTURAL ENGINEERING. 



A new dairy barn, A. M. S0V1.1: (Teiinessee Sta. Rpt. 1899, pp. 9-18., 

 jigii. 11). — A description, with drawings, is given of the barn completed 

 at the station in the early part of 1899, at a cost of about ^5,000: 



"The building is a frame structure 54 by 73 ft. 6 iu., exclusive of the silos, which 

 are 18 by 30 ft., and an annex which is 18 by 50 ft. . . . The silos are situated at 

 the south end of the barn, some 10 ft. being under ground. This brings them on 

 a level with the basement, and, as they open into the cow stable, it materially lessens 

 the labor of feeding. . . . 



"The annex on the west side of the barn in two stories high. In the basement 

 are .stalls for bulls and calves, while the upper story is devoted to the various wagons 

 and implements needed in farm work. . . . 



"The barn is built into the side of a small hill. By the construction of a retaining 

 wall, which also forms the foundation of the two interior sills, and by projecting the 

 barn forward on the face of the slope, a stable is secured opening on the ground level, 

 and yet sufficiently protected on the north and west to keep it warm in winter. Thi.s 

 leaves two faces of the stable foundation exposed, so that a continuous row of win- 

 dows on the eastern and southern sides gives ample light and ventilation. This 

 method of construction brings the second floor on a level with the ground, and no 

 artificial bridges are necessary to enter the barn. . . . 



"The roof is trussed from above so as to leave the storage space in the clear. . . . 



"The factory system of exposed structural timbers was followed in the construc- 

 tion of the stable, and the spaces between the supporting timbers are inclo.sed with 

 matched ceiling and the whole painted white. This gives an attractive appearance 

 and permits the walls to be washed whenever necessary. 



"The cow stable is situated in the basement, and is provided with a Portland 

 cement floor, having a sloising surface. . . . The mangers face the exterior walls of 

 the barn." 



The construction of the mangers and stalls is the same as in the 

 Wisconsin Station barn (E. S. R., 11, p. 595), except that it has been 

 found necessary for experimental purposes to provide divisions between 

 the mangers. 



' ' This has been cheaply accomplished by cutting out a section of board the shape 

 of the manger, hinging it over the lower angle of the stall division with hoop iron, 

 placing a 2 by 6 scantling at the near side of the manger, and fastening the division 

 tirmly by a sliding bolt lock. These partitions are so nicely adjusted that they 

 prevent the admixture of the different cows' feed, and at the same time just sufficient 

 space is left to enable the free movement of water through the entire length of the 

 feeding trough. Their mobility and ease of adjustment is a decided advantage 

 when it becomes necessary to scour the manger. Stalls are provided in the stable for 

 30 cows. 



"The basement also contains a stock-judging room where specimens of the differ- 

 ent classes of live stock are brought in and conveniently examined and scored by the 

 agricultural students. . . . Box stalls are provided also in the basement for sick 

 animals and for calves. Closets are conveniently placed for tools and other sundries 

 needed in the stable. The milk room occupies the southeast corner, and is parti- 

 tioned off from the main stal)le so that the milk can be innnediately removed and 

 kept where there is little danger of its being tainted. This room contains the aerator, 

 milk scale, composite sample jars, tables, and other accessories needed for keeping 

 the various records. The milk is innnediately aerate<l and cooled after l)eing drawn
