On the Quantity of Ashes to be obtained by Burnbaking.
A. St. Leger, Esq.

In August 1772 I pared and burnt one acre three roods of limestone land, and carefully collected the ashes into two heaps for a future experiment. Having so good an opportunity, I measured the ashes, and was much surprised at the quantity, being eighty cart loads, thirty bushels to the load.

I shall not here enter into the merits of burnbaking; but, from the above experiment, it is obvious that a complete dressing may be obtained, in any country, upon very reasonable terms.
