338 Observations on the immense 
her, and need not rely on fortuitous assistance from the shore.””— . 
Report of the Committee of the Hon. House of Commons, Jan.1808. 
My residence being near to the shores of Mount’s Bay, I have 
had opportunities of witnessing many melancholy shipwrecks; 
among others, that of H.M.S. Anson, when about 100. of her 
officers and men were drowned. The annihilation of this fine ship, — 
with so many of my fellow-creatures, deeply impressed my mind; 
and freshened in my memory the premature destruction of about__ 
fifty fine fellows at the wreck of the Jane-and-Rebecca transport; 
only a few weeks preceding, and also-near.the same spet. These. 
melancholy disasters Jed me into a train of reflection and reason- 
ing,,and I was very soon possessed by the idea of devising means 
for preserving lives from shipwreck.; From_that period have I 
been pursuing my object ;. and, happy for mankind, I have been 
made the honoured instrument in the hand of Providence, in de- 
vising such means as. possess. every probable efficacy to accom- 
plish all that is possible for the purpose so anxiously wished. fors, 
—and which, from inspection. and experiments made, have ob- 
tained general approbation.

rocket; when Mr. Trengrouse-exhibited his apparatus, and made 
the following experiment, 
Ist. A small rocket-of eight ounces, with a line.attached to its 
stick, was fired from a musket to the distance-of 180 yards. 
2d. A pound rocketiwas fired in the same manner, which ranged 
450 yards; the line broke.at 150 yards, owing to a_knot in it.
