Yet, as Mr. Sharp has engaged to finish the Plate before another Volume can be published, the Print will be prefixed to that Book; and it is hoped this will serve as an apology for the present omiffion.

Among the Papers inferted under the head of Agriculture, in the following pages,. it must givè fatisfaction to every intelligent Reader to obferve the advances making in that branch of the Society's attention.

The feveral plantations of useful Trees, and the judicious obfervations on the Chefnut, cannot fail to be highly gratifying to all Planters of Foreft-trees. The Paper on the comparative Merits of the Drill and Broad-caft Husbandry, exemplified by the very extensive experiments related in the Letters of Mr. Rogerfon, throws a very clear light on that fubject, which has for many years engaged the attention of the most celebrated Agriculturifts of this and other Countries of Europe, and will probably

bably tend to folve a question, allowed by all to be of the first importance to the Hufbandman and the Public. Another

object of great confideration with every Cultivator, has been to determine the neceffity of fallowing Land: the Letter from Mr. Dunn inferted in this Volume, relating an experiment of planting Potatoes on ground propofed to be fallowed, and the account of the value of the crop obtained thereon, will tend to elucidate that matter; and particularly fo, when the produce of the Wheat on that land fhall have been communicated to the Society.

The use of Potatoes in feeding Cattle and Sheep begins now to extend itself into many different parts of the kingdom; and fome of the advantages to be expected from that practice will be found by perusing the Paper from Mr. Bucknell on that subject.

When the use of Potatoes has become fo general throughout the kingdom as to fupply, in a great degree, the place of Bread, A 3 every

every attempt to guard against a failure of that useful root must be highly gratifying; and although the Papers of Mr. Hollins do not propofe a remedy or cure of the Curl, when the disease has taken place, yet, from very certain authority, it appears that his method of prevention has been in a remarkable degree fuccefsful; and as in the following sheets his mode of cultivating the Potatoe is clearly defcribed, it is hoped that any gentleman who may hereafter practise it, will favour the Society with fuch obfervations as occur thereon, that the Public may gain full information on a subject of fuch importance.

The Letter of Mr. Dann will fhew what advantage may probably ensue from the use of the Drill in the culture of Turneps; and a Paper received from the fame Gentleman, and for which the Gold Medal has been adjudged to him, but which came too late to be inserted in this Volume, will, when printed, more fully ascertain the compara

tive advantage of the two methods, in the culture of this ufeful and neceffary plant.

The great quantity of waste and uncultivated Land in this kingdom, is a constant and universal cause of complaint; and whoever travels over that part of the country where the improvements of Sir Thomas Hanmer have taken place, will observe with great pleasure the advantage arifing from them, but at the same time will feel a regret that an example fo laudable has not been more generally followed.

To procure within these kingdoms a fupply of Honey and Wax, has long been an object of the Society's attention; and in this Volume will be found three Papers on the fubject of keeping Bees, which, it is prefumed, will furnish much information on that head. The principal parts are written by perfons who have long kept those useful and industrious infects, and are become perfectly acquainted with the mode

of managing them and obtaining the honey, and this without any abftrufe theory; the fuccefs that has attended their labours having in a great measure arifen from care, and that best inftructor Experience.

To prevent the annoyance from the fmoke of Steam-Engines, and other large works, premiums have been offered during many years; and under the head of Chemiftry, in this Volume, is inferted a Paper propofing to condense the smoke arifing from Steam-Engines, in such manner as not only to prevent annoyance, but even to obtain a material of use and value. How far the propofition, in its prefent ftate, may be found worthy the adoption of the great Manufacturers, can only be determined by experiment; but it is probable fome useful hint will be furnished by that Letter, which, in time, may be productive of advantage; and fhould the method here propofed be adopted, any communication on the subject will be highly fatisfactory to the Society.
