The comparative cost; I don't know how heavy a wall we would need 

 to build. I have not done any figuring of the comparative cost of build- 

 ing such a silo, compared with the wooden one. 



Q. On the Burlington road, between here and Chicago, the abut- 

 ments and piers are all made of it. 



A. Elgin is building piers of it now. The engineer insisted that the 

 walls should be of brick and stone, but now after two or three months 

 have decided that the concrete is by far the better. 



Mr. Soverhill: All of the abutments O'n the canal are built of 

 cement. 



Mr. Stewart: To make a point here. Some six or seven years ago 

 I had one of these men that han dies this cement do a job- for me. He 

 wanted to use German cement, a nd did use it. But I have not used' any 

 now for five years. The cement I use is made in your own State. We 

 had to put on some of these iron hoops and it is as good as any cement 

 you can get. The man that did 1 1 lives in Aurora. 



Q. We have a silo where we have used that cement and it is not a 

 circular silo; it is in good working order. 



Q. What an the dimeDsions of it? 



A. I could not tell you that. 



Q. A square silo? 



A. No, an oblong one, with mighty thick walls. They need to be 

 thicker in a square silo than in a round one. 



Mr. Soverhill: You wouldn't build a square silo? 



A. No, sir, I would not bull d a square silo of any kind. I cannot 

 afford to; you don't preserve your silage, let alone the cost of building it. 



Mr. Crosier: In reference to this Portland cement, I know of three 

 factories using it. One of them a year ago this winter was being built 

 and a truck run over the f oundati on of it before it set, and those truck 

 tracks are as perfect today as th ey were a year ago. Ther0 is n-ei quesn 

 tion but that they will be the same fifty years from now. 



Mr. DuBois: You have not said a word about) your foundation. 



A. I put a grout, a circular grout, one where the building topped 

 the ground.
