STEAM BOAT CONVEYANCE. 



May 10, 1830. — In the morning we travelled by stage, from New 



rnoon 



Marshall to New York. This 



two boilers, on her wings, entirely over her sides, so that nei- 

 ther steam nor water can enter the cabins. The public are much 

 indebted to the Messrs. Stevens for the introduction of this excellent 

 arrangement ; for an explosion cannot affect the passengers below, 

 and both the chance and the mischiefs of explosion are diminished in 

 proportion as the boilers are smaller. 



May 11. — The steam boat Bellona conveyed us from New York 

 to Elizabethtown point, fifteen miles. There are two boilers in this 

 boat, also, one on each side, but both are under the deck ; this gives 

 more room above than if the boilers were on deck, but explosion will 

 of course fill the cabins with steam and boiling water, and the chance 

 of sinking, on account of injury to the bottom of the boat, is much in- 

 creased. This subject is worthy of the highest efforts of the great- 

 est minds, and a munificent reward should be offered by the govern- 

 ment of the United States for the discovery of an absolute preventive 

 of explosion, or an absolute security against its effects ; and for the 

 accomplishment of both objects, the reward should be doubled. 



The advantages of steam navigation are so great and manifold, 

 and to this country so indispensable, that they cannot be abandoned ; 

 steam navigation has become an integral part of the domestic policy 

 of the country, and will be pursued, even with all the hazard to life,
