fide, a very ingenious Architect, to compofe a Draught agreeable to the Ufe requir'd, and to the Rules of Architecture, which I fhall here prefent my Reader with.

It is neceffary to obferve by the by, that the Use of the Thermometer is chiefly in the Winter; when we make our Fires, or give artificial Heats, then we are to keep the Spirit up to PincApple Heat, or thereabouts, rather above than under that Point; but in the Summer Time, the natural Heat of the Sun when it is confin'd in a Frame, will be fo much, that the Spirit would be up at the Top of the Tube; but yet, that Heat in Summer, with the Addition of the Tanners Bark to the Roots, is no more than neceffary for the ripening of the Fruit, as the artificial Heat in the Winter is necessary for the Growth of the Plants.

For the Ufe of fuch as may propose the propagating or culture of the Pine-Apple in more fouthern Parts, the neceffary Directions are given in the following Letter, which I drew up on Purpose for Mr. John Clark, an eminent Merchant at Oporto; which, with that ingenious Gentleman's Answer to it, may be of good Ufe to help our Obfervations, and teach us to judge of the Difference of Climates; and that the Management of a Plant in one Climate, should be different from the Management of it in ano¬ ther Latitude.

To Mr. John Clark, Merchant, Oporto.

SIR,

TH

London, Jan. 28, 1723.

HE worthy Gentleman your Father acquaints me, that you have a Defign of propagating the Ananas or Pine-Apple in Portugal, the Method of doing which with us you will find in Mr. Telende's Account, and which I fuppofe Mr. Clark has fent you. But as your Climate has much the Advantage of ours in ripening Fruit of any fort, fo you must furely have extraordinary Succefs, though there muit be fome Alteration in the Way of Manage

ment.

In the first Place, your Sun is fo hot in the Summer Months, that the Glaffes of your hot Bed Frames would fcorch and burn your Plants, if they were to be cover'd in the hot Time of the Day; therefore I rather recommend Frames of Canvas to cover the Plants in the Time of the Sun's great Heats, and the Glaffes only to be put over the Plants about an Hour before Sun fet, to cover them a Nights, and keep a Body of warm Air in the Frame, till the Warmth of the following Day approaches; fo likewise in your hot Weather, the Plants will require more frequent Waterings than with us, but not more at a Time than we would allow them in our Climate.

Your

Your Seafon of Spring, I suppose, is about fix Weeks before us, and as much good Time for ripening of Fruit after us: But I would gladly know from you, how far I am right in my Conjectures concerning your Spring and Autumn Seafons; and alfo when your great Rains fall, which will help to inform us how to cultivate Plants that come from the Country where you are.

We have got a Thermometer for you, whereby your Heats may be regulated; but it is rather to direct your artificial Heat in Winter than in Summer; for your Summer Heats will fling the Spirit fo very high in the Glass, that it will be beyond Regulation; and as the Summer Sun is a natural Heat, fo it needs not be any otherwife regarded, than by keeping it from. fcorching the Plants.

This Inftrument fhews the Degrees of Heat or warm Air neceffary for Plants which grow near the Equinoctial Line, and from thence is mark'd upon the Scale the feveral Degrees or Proportions of warm Air requir'd for Plants which are Natives of Climates in feveral Degrees of Latitude, as far as 40, which is as much or more than we have Occafion to use in or about the Latitude of London, which is 51 Deg. 30 Min. for we find by Experience, that the Plants of Virginia, whofe Latitude in the most Northern Point is about 38 Degrees, will live abroad, and defend themselves against the Rigour of our Frofts. So likewife we have many Examples of Plants from the North of Carolina, whofe Latitude is about 34 Degrees, that will generally bear our Winters without Shelter: But from about 34 Degrees, to about 26 or 27 Degrees, we must
