very properly terms the ſubſoil; and, from

very‘common A ſee the water ſtand on ploughed land

where the furrows are quite open to the bottom; and by

digging a hole about the ſize of a half hosſhead barrel, I have ſeen it taken of to a good effed; and inſtances too are perpetually occurring of depthening ponds that will not hold water afterwards.

TIL. Proper materials for dreſling and altering the tex- ÉITerof the ſoil.

In the article of manure, Mr. Boys very properly takes

notice; that the ſea ie Es an inexhauftible ſupply of

ſand and ſhells, called Sea-ſhingle, that greatly improves'

arable land, To prove their uſe, I Will attempt it by compariſon. Strange as it may appear, it is very evident that all the low flat marſh-land in this iſland, ſuppoſed originally to be the ſediment of the ſea, is never too wet, notwithſtanding the ſoil is ſtiff; and the inſtant you af- cend the uplands they are found ſoft and wet in the win- ter ſeaſon; and a horſe would ſink over his paſterns, when not fifty yards below, the print of his ſhoe would ſcarcely berſéen eneland R 1s thus affe@ed loſes full half 1ts value: This wonderful circumſtance of the loweſt land being the moſt dry, I attribute to a portion of ſhingle or ſea-ſand, as I firſt mentioned in my deſcription of the ſoil, depoſited by the ſea, and occaſioning the ne- ceſlary filtration of the water through the ſoil.

I have only to add to the foregoing obſervations, that under-draining, and‘manuring with ſea-Mingle, appear to be the moft rational and adviſeable methods to improve the uplands of this ifland: and I recommend, as an ex- periment, under-draining with ſhells only.
