Round Plastered Silos. 407 



of the cement not coming in direct contact with the silage 

 juices. If care is taken in setting the brick so as to secure a 

 smooth face, pointing the joints carefully, it will not be nec- 

 essary to even whitewash the wall and a permanent lining 

 requiring no attention will thus be secured. 



In this form of silo the brick may have one face filled 

 with coal tar, or the vitrified paving brick may be used, 

 giving a lining wholly air tight and permanent. 



BOUND PLASTERED SILO. 



Where brick are high, lumber low, and clean, sharp sand 

 may be readily obtained, a cement plastered lining may be 

 made to take the place of the brick lining, usjing the Mil- 

 waukee, Akron, Rosendale or Louisville cement in making 

 the mortar. The first coat is usually made with hair and 

 a little lime to make it hang to the wall better. 



There are a good many of .these lathed and plastered 

 cylindrical silos in Racine and Kenosha counties in Wis- 

 consin, and across the line in Illinois. Some of these have 

 been in use since 1889 and have given good satisfaction. 



508. Construction. The frame work of the silo should 

 be made exactly like that of the silo with brick lining ex- 

 cept that there should be two layers of half-inch sheeting 

 on the inside with a layer of 3-ply Giant P. and B. paper 

 between, or other of as good quality. 



After the woodwork of the silo has been completed it 

 should be lathed and plastered with a cement mortar made 

 of 1 of cement to 2 of sand. 



If wood lath are used there should be furring strips of 

 lath nailed to each stud up and down and the lath nailed 

 through these. If metal lath is used this may be nailed 

 directly to furring strips of lath nailed to the studding over 

 the lining and the plastering then done. 



It should be understood that it would not do to lath and 

 plaster a rectangular wood silo because the springing of the
