purpose would be any boat from sixteen to twenty feet m 

 length, which is to be prepared as follows. 



Reference to the Plan of the Rev, Mr. Bremmer's Prepara* 

 ration of Ship Boats as Lifeboats , P/. 1 i I , Jig. 4 and 5. 



Two additional ring-bolts are to be fixed in the keel with- Preparation of 



inside of the boat. One to be placed one third of the boat's f ship's boatt.

 length from the stem. The other one third from the stern, nfeboat. 



Two auger bores are to be put through the keel withoutside, 



and close to the garboard stroke. One of these bores to be 



put about half way betwixt the ring in the stem, and that 



next to it in the keel. The other about half way betwixt the 



ring in the stern, and that next to it in the keel. 



Plugs may in ordinary be put into these bores, to be 

 struck out, when occasion requires. 



Those ring-bolts which are in ordinary in every ship's- 

 boat, the two additional ring-bolts in the keel, and the two 

 augur bores, are all intended as secure points of fixture, to 

 which seizing ropes are afterwards to be attached. 



In the next place, two tight empty casks, (see fig. 4.) are Casks. 

 to be provided, of such dimensions that their length may fit 

 to the \vidth of the boat, when laid athwart ship, and their 

 diameters to be about three feet, and if larger so much the 

 better. 



Each cask must be furnished with a sling on each end, 

 and each sling to have two eyes on it, about six inches asun- 

 der, and the slings so put on the cask as that the eyes may 

 be on the upper side when laid into the boat, that the seiz- 

 ing rope may pass through those eyes, in their way from ring- 

 bolt to ring-bolt. 



One of these casks, so prepared, is to be laid in forward, 

 and the other aft; and each cask so near its respective ring 

 in the keel, as only to leave sufficient room for passing the 

 seizing rope through the ring in the keel. 



By this means the vacant space, to be then filled up with 

 cork, will be left betwixt the cask and the bow forward, and 

 betwixt the other cask and the stern aft. 



The requisite quantity of cork, according to the dimen- Cork, 

 sions of the boat, and the quality pf the cork, may be about 



a hundred
