experience, so for this only do T prescribe. Having well con- 

 sidered where the liquid is to be used as well as where it is made, 

 and resolved upon the most convenient situation, I have a hole 

 dug full 7 feet in diameter and 12 feet deep, the bottom being 

 shaped like a basin and well rammed with a little water into good 

 puddle. The construction of the tank is commenced by the brick- 

 layer forming a circle with bricks (4 inch work) round an open- 

 ing of 5 feet, leaving a space behind the brick-work to be filled 

 and rammed well in with clay-puddle by the labourers as the 

 building is worked up, no mortar being used with the Ijricks or 

 anything else till the dome is to be formed ; mortar or cement is 

 then required, the roof is arched in, a man-hole left in the centre 

 of each, tank and covered with a 3-inch yellow deal cover ('2-inch 

 oak would be better). One of these tanks, containing 1000 gallons, 

 costs '11. \ls. 6c?. in the following items^ calculating to farmers who

Several of these tanks should be made adjoining each other ; they 

 then form a most excellent filter to keep back any hay or straw 

 that would prevent the egress of the liquid from the water-cart, 

 receiving it into the first from the stables, and pumping it out 

 of any other one of them. It must be observed, also, the tanks 

 being formed, the drainage into them is the next feature to be 

 considered. I have adopted a mode economical and elfectual by 

 laying down in the pavement what is called at the iron- works an 

 angle-iron gutter of very small size, and covering the surface of 

 it wdth a flat iron bar, just to lay within the surface of the gutter, 

 wherein all the urine is received and conveyed away imme- 

 diately, and all the straw^ dung, and dirt is kept out; this is 

 highly advantageous, as the urine is conveyed away immediately, 

 without escape of ammonia, and the little gutter may be un~
