THE SILO.

"Two men can make 90 to 100 blocks a day after they become ac- 

 customed to it. I used a wood mold which any carpenter can make and 

 will not cost over $1 or $1.50, at most. 



"Now as to the doors. I used 2x6 plank for the jambs and set 

 them flush with the outside of the wall ; as the blocks are 8 inches thick 

 there are two inches on inside for door to set in. The doors are 

 ship-lap doubled with a good quality of tar paper in between, also a layer 

 of tar paper on the side that sets against the jamb. The doors are 2 

 feet square and every 4 feet. Total cost about $225.00. The cost for 

 labor to fill it I estimate at $50.00." 



This is a cost of nearly $2.00 per ton capacity, but inasmuch as it 

 will last a great many years it may be the cheapest kind in the long run.
