of checks. The 14-ft. and ii-ft. studs are nailed to die side of 21-ft. 

 studs at the halved ends with two 4-in. nails to each stud. The last 

 check on the 21-ft. stud should then line with the first check on the shorter 

 studs. The 14-fi. studs take the place of the 24-ft. studs in a 69-ton' 

 silo. There are five port holes. The elevator, which is about 40 ft. long, 

 is supported as shown in drawing. 



The following is the additional material for a 102-ton silo: — 



Adoitional Material for a 102-ton Silo. 



Red-tjiim. 6-in. x 4-in. ; 8 g-ft. (No 6-ft. lengths required.) 



Hardwood, 4-in. x 2-1 n. ; 6 14-ft., 27 ii-ft., 6 21-ft. (No 24-ft. lengths- 

 required.) 



Hardwood, 6-in. x 5-in. ; 30 i8-ft. 



Oregon, 3-in. x i-in. ; 2 15-ft. 



Cralvanized sheet iron, 24 72-in. x 36-in., 24 gauge. 



Bolts, nuts, and rtaslver.s — 8 S-in. x. 5-in., 24 35-in. x g-in., 7c 2j-in. x |-in.,, 

 4 4-in. X f-in., 12 3-in. X |-in. 



Plate washers, 6 5-in. \ i in. x 5-i6ths-in., with 7-16-in. hole. 



Nails, 3 lbs. 4-in., 2 lbs. 2-in. 



Wire clouts, 3 lbs. 1-4-in., 2 lbs. f-in. 



.Additional Material for 40-ft. Elevator. 

 White deal, 6-in. x i-in. ; 15 20-ft. 



White deal, 6-in. x ^-in. ; 4 i8-ft. (No 15-ft. lengths required.) 

 Oregon, 6-in. x i^-in. ; i 3-ft. 



Chain, 20-ft., i g-i6ths-in. pitch. (No. 45 link.) 

 Slats anil attachments, 10, for No. 45 link. 



The additional c( '".t of material in Melbourne would be £^^, of which 

 £^i IDS. is for the elevator. 



Raising Height of Existing Silo. 



To' raise the height of an existing silo, the new studs should he halved 

 for a length of about 2 ft. and nailed with two 4 in. nails on to the 

 sides of existing studs. This means that all the studs are 2 in. out of 

 line with the existing ones. This will allow for boring and fixing the 

 new studs without removing anytliing except the roof. 



ALL WOOD SILO. 



This is not a stave silo. It is the barrel and hoop type, like the wood 

 and iron silo, the iron being replaced by the wood lining. Those already 

 constructed in the Alexandra districf^ have several defects in regard to 

 their strength, which have been remedied in the descrij^tion here given. 

 This form of silo is likely, in the moist districts, to give satisfaction, and it 

 is certainly cheaper than any other type yet adopted. If the farmer will 

 provide the hardwood, as in the list following, a considerable saving in 

 freight and cartage should result. The weight of roof and elevator material 

 is only 8 cwt. for the 70-ton and g cwt. for the 106-ton size. 



Directions for Building A-yo-TON Silo. 



(75 ft. inside diameter and 20 ft. highf) 



Foundation. — Prepare eight foundation posts of 6-in. x 4-in. red-gum 

 6 ft. long. Round or split posts will do as long as one side is dressed flat; 

 in this ca.se, it is probable that longer bolts will be required than for sawn 

 timber .
