306 BULLETIN No. ] 10. [July, 



south. Each lot is enclosed by a board fence 4 feet 8 inches high. 

 All lots are paved with brick. The sheds are not paved. These 

 lots have gates leading into each other, to the alley, and out of the 

 south end of the lots. There is also a gate in each lot so placed 

 that it, together with the gate between the lots, can close the space 

 between the fence and feed bunk, thereby making it possible to con- 

 fine the cattle under the shed while the lots are cleaned and in the 

 lots when the sheds are cleaned. Each lot is furnished with a feed 

 bunk for concentrated feed and two mangers for hay. One water- 

 ing tank is provided for two lots. Plates 9, 10, and u. 



PAVING 



The grade used in paving these lots was one slightly above the 

 surrounding level and given enough slope (6j4 inches from north 

 to south and 3*4 inches from east to west of each lot) to allow the 

 water to run to the south-west corner of each lot where tile were 

 laid to carry it away. 



After the proper grade had been secured the ground was cov- 

 ered with six inches of gravel which was rolled and tamped down 

 solid, covered with one inch of fine sand upon which No. i paving 

 brick were laid flat, (herring-bone pattern, Plate 12) except in the 

 alley and around the scales where they were placed on edge. After 

 being put in place, the brick were rolled down even and upon inspec- 

 tion, if any were found to be soft, they were replaced with good 

 ones. 



The space between the brick was filled with a grout "filler" con- 

 sisting of one part clean, sharp, sand and one part of Portland 

 cement. The cement and sand were thoroughly mixed dry in tight 

 boxes, then made into a mortar of the consistency of cream and 

 thoroughly broomed into the joints. The slushing was repeated to 

 insure the filling of all cracks or joints between the bricks. This 

 was done to keep water from getting underneath the pavement; 

 which, if allowed to enter, would soften the subgrade or cause the 

 heaving of the brick by alternate freezing and thawing. 



The cement filler was allowed to set a week before heavy loads 

 were allowed on it and as the work was done in summer, the sun's 

 rays were kept off by means of a canvass for the first day. A re- 

 taining curb of 2x8 plank, braced by a 4x4, placed 2^ feet in the 

 ground, was put in at the gates to keep the animals from breaking 

 the edge of the brick. Next to the shed, 3x8 oak plank were used 

 for curbing. Where there are mangers and fences, the bottom 

 board was placed low enough to act as a curb. Plate 12.
