The principle of this invention comprehends any speciesof machinery thus put in rotatory motion hy a steam engine, whichmay he made use of to navigate boats, vessels, or rafts. Second, tobreak ice, a number of beaters, hammers, or stampers may be placedin the bow quarter of the boat, vessel, or raft, which beaters, ham-mers, or stampers, when put in motion by the steam-engine, may re-volve upon an axis, or be worked by an up and down motion in mannerof common tilts or stampers. (Signed) William to <a z Zi a DC -to s < UI o •< STEAM NAVIGATION. 57- About the year 1825 Mr. Symington was induced to present a to the Lords of his Majestys Treasury, in consequence ofwhich the sum of £100 was awarded from his Majestys privy purse,and a year or two afterwards a further sum of £50.

In the decline of life he appears to have had several kind relativesand friends who contributed to his support; and among the num-ber was Lord Dundas.
