Steamers, 1811, 1874. John Hamilton.

 fitted with Price's patent has effected very large saving in the cost of loading, 

 as trimming is entirely dispensed with. The pamphlet containing testimonials 

 explains the opinions of the owners, who have adopted the invention. 

 With a lithograph showing profile of vessel fitted with Price's hatchways, 

 also detailed sketches of manner of fitting half-booms, hatch sides, &c.
