The Best Means of applying Liquid Manure. 29 
of Italian rye-grass grown. This is on the supposition that the 
tanks are emptied every day ; but in order to provide for the 
accumulation which takes place on Sundays, or during a tempo - 
rary stoppage of the machinery, it is necessary to ha^ e additional 
tanks, which can be provided by each one, according to his own 
requirements, in accordance with the rule here laid down, that 
each day will fill a tank containing 175 times as many gallons as 
tliere are acres of Italian ryegrass grown for soiling. 
The following calculations show the expense of the field- 
apparatus {i. e. pipes and hose) of this liquid-manure system. 
(1.) On a farm of 408 acres, where the whole field is treated as 
under the present system — with pipes under the whole ground, and 
hydrants at intervals all over it. (2.) On the same farm, where 
an underground main pipe is supplied with portable surface 
pipes, to serve for |ths of the surface. The other tables (3), 
(4), (5) are sufficiently explained by their respective headings.

and at the same time the tear and wear from corrosion of the pipes while 
out of use is avoided. The continuous and active use keeps up sulBcient 
friction to greatly stay the progress of corrosion in the pipes.
