at a time when lumber of a good quality could be secured at 

 a much less cost than at present. In brief its construction is as 

 follows : Studding of 2x4 stuff is placed one foot apart on a 

 circular sill on top of the foundation. The lining of the silo 

 consists of three layers of j^-inch boards bent and nailed to 

 the studding with building paper between. The studding is 

 covered on the outside with one layer of JHrinch sheeting and 

 then with any form of siding which may be bent and nailed to 

 the studding. If the silo is of small diameter, the sheeting 

 may be omitted. In keeping silage the King silo is very satis- 

 factory and when the wall is ventilated in order to prevent rot 

 on the inside, it should be as durable as any wood silo. 



The Gurler Silo. 



The Gurler silo was designed by Mr. H. B. Gurler, and 

 the first silo of the kind erected fourteen years ago was visited 

 and found in good condition. The Gurler silo resembles the 

 King silo very much, but differs mainly in that the lining is 

 made up of a y 2 -mch layer of sheeting and cement plaster 

 about y 8 -inch thick on special lath. It is primarily a silo to be 

 located inside of the barn and when so situated the only covering 

 to the studding consists of wooden hoops made of three-ply 

 of T / 2 by 6-inch boards. When used outside vertical siding 

 may be nailed to the hoops, which when well battened makes 

 a very satisfactory covering. The hoops may be dispensed 

 with and the studding covered with galvanized sheet iron. This 

 plan is very satisfactory, but perhaps a little more expensive 

 under usual conditions. Horizontal siding bent and nailed 

 to the studding is not generally satisfactory, as the 

 nails will pull out, releasing the ends of the boards, which 

 often in time come off entirely. As stated, the Gurler silo is 

 not primarily a silo for a location outside of protecting build- 

 ings, as the action of the wind is quite apt to rack it and cause 

 the cement plaster to crack. This can be prevented to a large 

 extent by placing the hoops on spirally, thus stiffening the silo 

 very much. Under usual conditions its cost is somewhat greater
