'Idle importniu-o of

 liuiiud with iron tie- 

 riids is ver.v great, not 

 (iiily to resist the in- 

 ternal pressure of the 

 ensilage while heing 

 made, hut in a greater 

 degri'e to keep the liar<l- 

 wood studs from warp- 

 ing or twisting away 

 from one another at the 

 joints under the intlu- 

 eiice of the weatlier. 

 From the nature of the 

 di'sign, an.v tendene.v to 

 deviate from the straight 

 in an inward direction 

 would only cause a. 

 t igliter and hetter joint, 

 hut when the grain of 

 the studs would cause 

 an outward heiid this is 

 resisted hy the iron tie- 

 rods, and thus a ])erfect 

 joint is maintained. 

 A\'ith tile iron tie-rods 

 and the take-up nuts at 

 eacli joint, a perfectly 

 rigid and t-ask-like 

 structure is obtained. 

 The iron rods also stay 

 the intermediate studs, 

 and make the whole 

 frame as rigid as the 

 best class of wooden tub 

 silo.
