A PORTABLE SILO. 



E. A. Ryland, Silo Supervisor. 



Seeing that the modern metiiod of conserving succulent fodder by 

 means of the silo is a question in which all stock owners are vitalh in- 

 terested, perhaps a brief description of a simple and useful invention 

 in the way of a silo will be appreciated by the readers of the Journal. 

 The silo under review is manufactured by Mr. A. H. Russell, of 276 

 City Road, South Melbourne, and is made entirely of iron, in circular 

 sections 9 feet high by 6 feet in width. These are of a convenient size 

 for* two men to handle, and are made up of three sheets (6 feet by 3 

 feet) of 24 gauge galvanised iron securely jointed by double folding or 

 lapping. The outside studs or supports, of which there are three to a 

 section, are ij x | steel angle iron.. To these the galvanised iron is 

 securely rivetted by strong rivets placed at intervals of SJ inches apart. 



loWER HALF OF SILO SHOWING SECTION. 



The circular shape is kept by two angle irons running horizontally, 

 one at the top and one at the bottom of the section. They are bored with 

 § inch holes on the flat so that the bottom section may be secured by 

 spiking or bolting to sleepers or blocks in the ground, and by this means 

 the silo can be made a permanent fixture if so required. The second 

 section is secured by simply bolting it to the bottom section by means of 

 the band of angle iron. The capacity of the silo is increased or decreased 

 by the number of sections used, according to the quantity of fodder to be 

 conserved. 



The iron studs are conveniently bored to allow of the silo being stayed 

 when empty, by means of wire guys; the studs also admit of a ladder 

 being fitted to the side for access to the portholes. The joints between the 

 sections are packed by a strip of steam packing material, and thus the 

 whole silo when erected becomes practicalh airtight. The portholes are 

 made one to each six feet in height, the same distance apart as in the 

 silos built by the Department of Agriculture. The doors, constructed of 

 the same material as the wall, are attached outside by bolts and nuts, 

 three on each side bolted to the iron stud.
