The most numerous fish are herrings, cod, mackerel, ling, haddock, plaice, sole, fluke, turbot and brett. The industry is, however, in a decaying condition, especially the herring fishery, which fails periodically. The amount of fish caught, except herrings, is not sufficient to supply the demand in the sum mer. About 25o vessels, aggregating 4,260 tons, with crews num bering 4,250 are employed in this industry. A fish hatchery and marine biology station has been established at Port Erin.
In proportion to its area the metalliferous wealth of the Isle of Man has been considerable, but little or no mining is done to-day. Two of its mines, Laxey and Foxdale, have produced lead and zinc for many years. Copper pyrites and haematite iron, and small amounts of the ores of nickel and anti mony have been found. The mines are rented from the Crown as lord of the manor. Other economic products are clay, granite, limestone, sandstone, slate and salt. The principal manufactured articles are woollen cloths and blankets, hemp ropes and cotton, and herring nets. A few fishing vessels are built, and brewing is a prosperous industry. The most important occupation of the
people is that of the provision for summer visitors, half a million of whom come to the island annually. The chief exports are turnips, ropes, cotton nets and salt. The imports consist chiefly of timber and various foodstuffs.

Moore's History of the Isle of Man has a list of MSS. and books up to 190o. Other more recent books include:—P. M. C. Kermode, Manx Crosses (1907) ; E. A. Jones, The old Church plate of the Isle of Man (1907) ; A. Herbert, Isle of Man (1926) ; J. J. Kneen, Place names of the Isle of Man (1927) ; G. W. Lamplugh, Geology of the Isle of Man (Geol. Surv. 1913) ; A. W. Moore, Surnames and place names of the Isle of Man (1906) ; P. G. Ralfe, Birds of the Isle of Man (19o5) ; P. M. C. Kermode & W. A. Herdman, Monks Antiquities (1914) ; Hall Caine's novels have no doubt tended to popularize the island as well as a novel entitled The Captain of the Parish, by John Quine.
