Our author next proceeds to detail his experiments oncements ; but as they constitute no part of the building pro-cess, the reader is referred to the articles Cement and Mor-tar, where the subject is duly considered.

On the oth of June, 1757, the operations on the rock wererecommenced, and by the 10th all the preliminary matterswere settled; so that “on Saturday, the 11th of June, thefirst course of stone was put on board the Eddystone boat,(see Plate III. Figure 1,) with all the necessary stores, tools,and utensils. We landed at eight on Sunday morning, the12th of June, and before noon had got the first stone into itsplace, being that upon which the date of the year 1757 isinscribed, in deep characters ; and the tide coming upon us,we secured it with chains to the old stancheons, and thenquitted the rock till the evening tide, when it was fitted,bedded in mortar, trenailed down, and completely fixed ; andall the outward joints coated over with plaster-of-paris, toprevent the immediate wash of the sea upon the mortar.This stone, according to its dimensions, weighed two tons anda quarter. The weather serving at intervals, it was in theevening of Monday, the 13th, that the first course, consistingof four stones, was finished; and which, as they all presentedsome part of their faces to the sea, were all of moor-stone.

“ The next day, Tuesday the 14th, the second course (seePlate III. Figure 2,) arrived ; and some of it was imme-diately landed, proceeded with, and in part set the same tide:the loose pieces being chained together by strong chains,made on purpose for this use, and those ultimately to the stan-cheons, or to lewises in the holes of the work Course I. thathad already been fixed. The sea was uncommonly smoothwhen we got upon the rock, this evening’s tide, but while wewere proceeding with our work, within the space of an hourand a half, the wind sprung up at north-east, and blew sofresh, that the Weston, lying to deliver the remainder of hercargo, had some difficulty in getting out of the gut; and, hadit not been for the transport buoy, to which she had a fasten-ing by a rope, it would probably have proved impracticableto have got her out again. And we soon saw it was necessaryto get everything in the best posture time and circumstanceswould admit, in order to quit the rock with safety to our-selves, and security to what we must necessarily leavebehind us.

“ The pieces that were fixed and trenailed down, weresupposed to be proof against whatever might happen; butthe loose pieces, and those that were simply lowered downinto their dovetail recesses, were considered as needing someadditional security, to prevent their being carried away bythe violence ol the sea. Of the thirteen pieces of whichCourse II. consisted, five only were landed: No. 1 wascompletely set; No. 2 and 3 were lowered into their places,and secured by chains ; and No. 4 and 5, which lay at thetop of the rock, were chained together, and also to the slide-ladder, which was very strongly lashed down to the eye-bolts,purposely fixed on the rock lor that intent.

“In the evening (of June 15,) we made a short tide uponthe rock, and had the satisfaction to find that no materialdamage had happened to anything; we therefore proceededwith our work, and completely fixed No. 2 of Course II.On the morning of Friday the 17th we again landed for ashort time; and, notwithstanding we did not meet with any-thing amiss on our return to the rock on Wednesday even-ing, after the hard gale of wind, yet this morning we founda part of the rock in the border of our work, that secureda corner of No. 3, was gone : we therefore, to secure thatstone to its neighbour, applied an iron cramp, of which wehad some in readiness in case of accident. We were preventedlanding in the evening, by a fresh wind and rain at north-

west, but landed again on Saturday morning’s tide, ^ glV ellHowever, we had not been long there before a §1 ^ ge0arose from the south-west; and, though there h® ^ fast*wind apparently to oecasion it, yet it came upon ^ getthat we were obliged to quit the rock before weour work into so satisfactory a posture of defence as ^

It was, however, as follows: No. 1, 2, 3, 4, an ftte ’d,completely fixed as intended ; No. 6 and 7, were * ^ jut olowered upon their mortar-beds ; No. 8, was simp u ponits place, with a weight of lead of five hundred yveI ° n ta^ eit; which, in all such trials as had hitherto e s toP^thereof, had lain quietly. Not having time to g et i'° c *No. 9, into its place, we chained it upon the top 0 s< jay.to the slide-ladder, as we had done before on * ae ff ere athis condition we left the rock, having staid till Wwet from head to foot. _ k 0ll t 0 °°^

“ The storm continued till Tuesday morning '■ a j^viaHof that day,” says Mr. Smeaton , “ the wind and {0 ro''"become still more moderate, I judged it practica tbe*£ahead against it, so as to get to the westward o 0 nraud reconnoitre our damages : accordingly, taking ^ s er'' ea ’in the light yawl, it being then near low water, tb®* 1
