SILAGE FOR SUMMER FEEDING. 
As methods of farming become more and more extensive, farmers will come 
to use silage as a part ration during the whole year. The silo must ultimately 
supplant the pasture, except as a place for airing and exercise, and no other 
method of soiling can prove as economical as the silo when properly constructed 
and handled. 
If silage is fed every day in the year from a single filling, either more than 
one silo must be used or else the depth of the silo must be increased to about 
40 feet, and in this case the rate of feeding could not exceed an average of 1-4 
inches per day. Stillit is my judgment that this rate of feeding is preferable 
to having two silos, for I have shown that the loss from spoiled silage at the 
surface after 180 days, when this is used as cover, is 22 lb. per square foot or 
5'1-3 tons for a silo 25 feet in diameter. ;

A LABOUR-SAVING TOOL. 
By PHILIP MAC MAHON, 
Curator, Botanic Gardens. 
Tx every operation nowadays, from the sinking of a squadron to the hoeing 
of a cabbage plot, two things make for success. These are machinery and 
organisation ; and the man, bé his position what it may, who fancies that he 
can afford to neglect either, will certainly get “left.” If he is owner or 
Heer his business will leave him; if he is a worker, he will leave his 
Siness,
