with a tonnage of 6,654 '> m the latter year the 

 steam-ships numbered 627, and had a tonnage 

 of 28,271. The introduction of the use of ice, 

 which took place about 1850, and the invention 

 of various methods of renewing and aerating the 

 water in the fish-tanks, enabled the boats to 

 remain longer on the fishing ground, and to waste 

 less time voyaging to and fro to the port where 

 the fish is landed. Further, the time spent on 

 the grounds has been appreciably lengthened 

 by the employment of " carriers," which collect 

 the fish from the fleet of trawlers and carry it 

 to port. There has been a great growth in dock 

 and other accommodation. Since 1852, when 

 the Manchester, Sheffield, and Lincolnshire Rail- 

 way Co. opened their new docks at Grimsby, 

 the accommodation has. steadily grown, until 

 it now* covers 100 acres ; the population, which 

 sixty-five years ago was under 4,000, now* 

 exceeds 60,000. In 1854 the Railway Company 

 despatched 453 tons of fish ; forty years later 

 they were handling 80,134 tons, besides an export 

 trade which, however, has not expanded in like 

 ratio. The Great Eastern Railway in October, 

 1906, opened a new dock at Lowestoft. New
