SHIP*S LIFEBOAT. j^$ 



«nd with two eyes on each sling, and these eya* so placed as 

 to be about two inches above ths horizontal diameter of the 

 cask, one eye being on each side of the cask when the sling 

 is put on. 



The seizing-rope, being now made fast to the ring in the * 

 stem, istobepassedthroughtlie eyes on the slings on oneside 

 of the cask, then througli the ring in the keel, and so back ^ 

 again through the eyes on the slings on the other side of the 

 same cask, to the ring in the stem. The rope is then conti- 

 nued on till it has passed in the same manner on both sides 

 of the adjoining cask, and the last turn is to be made directly 

 from ringbolt to ringbolt, passing over and above the sur- 

 rounding rope, which will thereby be brought down in the 

 middle betwixt the twd casks, and made closely to compress 

 them on each side. 



The same process is to be followed as to the casks aft, 

 where the dimensions of the boat will admit of it, and where 

 otherwise one large cask athwart ^hip may be used, as in 

 the plate, fig. 5. It was in this manner that the experiment 

 at Leith, hereafter to be detailed, was made, and all the 

 cork that was used on that occasion was about one hundred 

 weight put into the narrow part of the boat aft, in order to 

 raise a common porter cask placed above it to a convenient 

 height. The preparation of the cork bundles in this case 

 will differ somewhat in their shape from those in the former 

 plan, but as the purpose of them is the same, namely, t<> 

 fill up the vacant spaces betwixt the cask and the boat, a 

 particular description of them seems quite unnecessary; 

 only it may be observed, that as the diameters of the casks 

 forward are considerably less than that in the former plan, 

 so much of the cork ought to be placed underneath, as may »,0\f, Htff![> 

 serve to raise the upper side of the casks about four inches 

 above the gunwales, it being evident, that the higher they 

 can be raised with sufficient security, the more effectually tiil 

 possibility of overturning will be prevented. 



The same quantity of ballast is to be used in this case atf 

 in the former, and is to be applied in the same manner. 



With respect to boats of small vessels, a single cask for- Boats of smaU 

 ward and another aft, without any cork, will be sufficient, ^"sels. 



Each cask to be about the size of a hogshead, and to be 



set
