Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed.

It may therefore in some situations be better economy to make use of the stones that are there, there, if large, though rounding, and to fill all solid, than either to break them to render them angular, or fetch this kind of stones from quarries within land. It seems therefore probable that something may be done by way of easing the expense, and increasing the expedition; but the proper mode of operation depending altogether upon local circumstances, I am unable to form my opinion fully thereon without a view of the premises.
