WIicii the manure was delivered throujjli the pijjes, it the pump 
■worked well and the manure was free from solid matter, a barge 
was emptied in two hours, though half a day has been allowed in 
the above estimate.* 
A trial was made of the Belgian fashion of applying liquid 
manure. On this plan, the cart is halted at the edge of the 
field. The cart is emptied into tubs with handles, of the size 
that two men can carry between poles, which are so put down 
that a circle having a radius of from 10 to 16 yards may be 
watered by the contents of each, about 33 gallons. The trial 
was made with mangold of considerable size, not well suited for 
Avatcring by a jet. The workmen were not experienced in labour 
of that sort ; but, on the other hand, they were always within 80 
yards of the cart, whereas in the North they travel as far as 200 
■or 300 yards. The cost was as follows : —

The men emptied 16 tubs, containing 528 gallons, at a conse- 
quent cost of 55. \0d. ; or, including the charge for dead stock, 
6a'. per ton. It must be admitted that with 2 water-carts, 1 team, 
and from 14 to 16 workmen, if the roads be good and the distance 
do not exceed 3 furlongs, 15 tons per day might be distributed. 
The wages for 14 workmen and a carter would then amount to 
■375. 6fZ. ; the horses, as before, to 65. 8rf. ; and the price per ton 
to about 35. ; or, if the charge for pumping and dead stock be 
added, 35. ^d. per ton. 
It is here assumed that the work goes on smoothly, without 
hindrances, which is rarely the case ; and still it appears that 
this highly-vaunted system costs 2 J times as much as delivery 
direct from the cart, times as much as that from the cart 
filled from the main pipe, and 6 times as much as irrigation 
by the jet. 
These results are in conformity Avith the general law of pro- 
* Some corrections are afterwards made which raise the cost of distributio e 
through pipes to 2s. 2d. per ton, in consideration of a deficiency in the amount 
manure distributed, and an increase of the cost of the apparatus above the estimate®'
