out any such diminution, as circumstances shall indicate.

For effecting these purposes, the devices are so simple as to run little risk of having any parts of the apparatus put out of order, and the original expence of constructing the houses will be lefs than those in use at present; besides, glafs of any kind that may be on hand at present may be so modified as to admit of being converted to the uses here, mentioned with very trifling expence.

I am aware that by merely stating these particulars without explanations, I run the risk of being accounted a visionary; but the time is not, I trust, at a great distance when I shall have an opportunity of removing that stigma by a full and distinct explanation of particulars; for I have little doubt but such arrangements may be made as to admit of this being done in the course of the next (the fourth) volume of this work. It is hoped my correspondents will accept of this as a sufficient apology for this small delay.

To the Readers of this Work.

THE Editor cannot conclude this volume without tendering his most sincere thanks for the candid indulgence with which his readers have received the humble and imperfect efforts that he has made for their gratification; an indulgence that has impressed his mind with sensations which words are too feeble to exprefs-a liberality on their part which imposed upon him claims that he considered as irresistible, to perform, with the utmost punctuality pofsible, every part of the contract that he had engaged in for the accommodation of his readers.`

With these sensations operating upon his mind, he has felt himself exposed, during the progrefs of this volume, to a series of mortifications that have proved highly distrefsing to him. Owing to the misapprehension of parties, or other circumstances, he was astonished to find, upon receiving the thirteenth number, (which he did not see till it was all printed off) that it had been printed upon a paper so much thinner than that which had been formerly used. He went to town immediately, and gave the most positive orders to get paper of the former qua

tily, without regard to expence, strictly charging the printer not to work a sheet on paper of an inferior quality; yet inferior paper has still been used. No lefs than three times in the course of this volume has the same practice been repeated; and it was not till he at last gave orders to have paper made on purpose, to be at all times in readiness, of the same quality, that he could have any certainty of having this matter duly adjusted: that paper is now in the printing-office for the next volume; the last half sheet of this number, as well as the index (being one sheet more than the regular quantity), has been worked upon that paper: and he has received the most positive afsurances, that in future no circumstance of this unpleasant nature shall again take place.

The Editor has experienced also a similar kind of vexation respecting engravings. Though he came under no positive engagement with his readers on this head, yet it was his wish and his intention to give figures well engraved, wherever the subject should require it: but in this respect he has been repeatedly disappointed. For want of a pofsibility of getting the engravings executed at the time he wished, he has been frequently obliged to set aside efsays that were intended for insertion, and to substitute others in their stead; or to publish the former without the illustrations that he had prepared. At the present moment an essay is lying in the printing-office, the types of which have been set up for more than four months, for want of an illustrative figure that should accompany it; and another, a communication from an ingenious correspondent on a particular mode of constructing drains, has been lying in the printer's hands many months, for the want of an illustrative diagram. Thus has this work been made to assume a niggardly appearance highly unworthy the character of a gentleman on any occasion to countenance; and under the relation that the Editor stands in to his readers, superlatively disgraceful to him.

These circumstances operated so strongly on his mind, and gave him so much disquietude, that he had determined at one time to stop the publication entirely at the close of the present volume; for, instead of a pleasing recreation to him, as the work would otherwise be, it became a task of the most distrefsing kind: but the respect that he owes to his readers overcame that hasty resolution. He recollected, that several subjects were begun which could not be finished in this volume; and that it would be an ill return for their indulgence to him, to leave them with an imperfect work. From this consideration chiefly, he relinquished that idea. Should he again experience a failure in these particulars, he will on no account subject himself to a series of such vexations, and will quietly desist; but his readers may rest assured, that if this event should happen, he will take care to finish the subjects that shall have been commenced, so that they may be left in possession of a work complete at least as far as it goes. It is his wish to visit the Netherlands, should a peace take a place, in order to make himself fully acquainted with the rural economy of that country; in which case he fears he shall be obliged to suspend his publication, not daring to rely on the regularity of others: but this he will not do in an abrupt man

er.
