of 6 in. mesh, and a few diagonal l)ars to distribute the weight. 

 The columns are re-inforced with four i in. indented bars, tied 

 at intervals of 12 in. by ^^ in. iron wire. The panels are 4 in. 

 thick, and have bars placed horizontally and vertically at 18 in. 

 centres. The smaller roof principals are 14 in. by 7 in., and 

 were formed on base boards 7 in. wide, by means of the wall 

 moulds. The ends of the base boards had wood blocks bolted 

 to them, cut diagonally to make fillets with the columns ; the 

 base boards were supported on poles, and these were left under- 

 neath until the concrete had set. The larger roof principals

are 18 in. by 9 in., and 28 ft. span, and the whole calculated 

 for a load on the roof .of fifteen pounds per square foot (Figs. 

 8 and 9). 



The aggregate for all this work was made from crushed 

 oolite and cement, in the ratio of six to one. For the stall- 

 divisions and mangers, 3 in. thick granite chippings were used, 

 and the ratio to the cement was three to one. The partitions 

 (Fig. 10) are 4 in. thick and 5 ft. 6 in. high, and are re-inforced 

 with six l)ars, one 18 in. from the ground, two at 3 ft., two at 

 4 ft. 3 in., and one at .5 ft. 3 in., the double bars being inserted 

 at the point where a beast exerts its weight. The floor is also 

 of concrete, and as the whole structure is jointless it is most
