T«* Fusing Business it* Gloocistx* Acorrespondent of the Buslon Traveller, says thatwhile the Fisning business of Marblehead has! greatly declined, that of Gloucester has largely in* j crossed In 1830, Gloucester employed in her fisheries 80 small vessels and 500 men ; ilus year j she employs 100 vessels, of an aggregate tonnage of 14,000 loot, manned by 20U0 men and boys-Thirty-five vessels have been added to the fleet this year j some of these aro to replace those that have been sold Seventeen packing establishments, with all the conveniences for pursuing the holiness, are conveniently located on variouswharves. 1One of the causes of this contrast betweenGloucester and Marblehead is this—that Glouces- H ter harbor is so much more convenient and oapa- . •but. The people of Marblehead have to haul up | tWr vessels in dalem m winter, such is the ex- p posed state of Marblehead harbor. The same rea- j sons havo partly caused Nantucket to decline most! l sensibly for the last ten years, while at the pres-1 •nt time New Bedford,with gieat facilitios for busi-l x ness, it progressing at sq unprecedented rate. IBoth Gloucester and Marblehead have sustained b great losses for the last ten years on George’s and I the Grand Banks, but the per centage #f lost has V been far more at Marblehead. |Besides the extensive fisheries of Gloucester * preper, as alluded to, the little soves and harbors I round Cape Ann such as Rod port, Pigeon Cove, Lane’s Cove, Flt;joam Foint, employ many small | r vessels and boats in the shore and mackerel fish-1 eries, and the aggregate of the disuict exceeds 5that of any other in the United States in this important business.
