as it is termed, around the external circle of broken chalk, 3 feet 
deep and 3 broad. This trench must be filled with chalk 
rubble ; and the object is to give a firm standage for cattle drink- 
ing at the pond, and to prevent the ill effects of their trampling 
and displacing the edges. 
If it be necessary to make a pond on the slope of a hill, then 
the method recommended by Sir Tatton Sykes, of Sledmere, is 
worthy of consideration. The common way of making a pond in 
such a case used to be thus —

C, the chalk embankment for the lower edge, consisting of the excavated chalk. 
d to e, water-level. 
Now this, though convenient for the sake of disposing of the ex- 
cavated matter, was found to be attended with the disadvantage, 
that the chalk embankment rarely obtained due solidity, and the 
water was apt to escape. The improved method may be de- 
scribed by the annexed section.

Here it will be seen there is no chalk embankment ; the water- 
level at point e rests upon the solid undisturbed strata, and there- 
fore there is less risk of leakage. The excavated materials are 
entirely carted away — at some additional cost certainly ; but a cost 
which is well repaid by the security of the pond holding water. 
It is thought that the Wold ponds made in this way, and once
