The IROQUOIS. — This boat, which is to ply between Prescott, and the head of the Long Sault, was towed from Gananoque to Prescott, on Wednesday the 9th. Inst., by the Sir James Kempt, where she is to be finished. The Grenville Gazette says, -- "her length is 120 feet, exclusive of wheels, which are to be in her stern; her width 18 feet. Ladies' cabin 20 feet, and gentlemen's cabin 43 feet; draws 12 inches of water, including keel. She is to be propelled by two engines of 25 horse power each, and is expected to be ready early in June."
A melancholy accident, if accident it can be called, took place of Colchester point, about five miles from the mouth of the river, on Tuesday afternoon. The American schooner Mariner, under full sail, was capsized in a squall and an entire family of Emigrants perished in the cabin. Just blame is attached to the Captain of the Mariner. He is represented as carrying full sail, under every indication of a tremendous squall. It is said that one of the Steam Boats passed within a mile or two of the wreck without giving any assistance although guns were fired from a schooner which had gone to her relief.
EMIGRANTS. — The Niagara steamer, on Sunday morning brought up three English families, 13 in number — and the Queenston, on Tuesday morning, landed 25 Irish, from Waterford, and 10 English Emigrants, and carried 12 to Hamilton, having landed 25 at Port Hope.
The William the Fourth v steamer arrived here at 6 o'clock this morning from Prescott, where she brought 260 emigrants — 40 cabin and 220 deck passengers; 110 of whom, chiefly English — landed at Port Hope, and 25 at Cobourg — the rest, about half of whom were English and half Irish were landed here or proceeded to Hamilton — chiefly to the latter place on their way to Guelph, &c. Many of there emigrants came out in the Marmion from London, and nearly all appear to be persons of respectable standing and circumstances — as farmers and tradesmen. There are some very fine families of young men and women.
As near as we have been able to ascertain, the total number of emigrants who have come up this season, from Quebec and from New York, in steam boats and schooners, is 493; of whom have been landed, -- In the Newcastle District , 195 -- York, Hamilton and Niagara, 289 = 493.
This is the first trip made by the William the Fourth, the new boat that has just been built at Gananoque. She is a remarkably handsome vessel, both in external appearance and internal arrangements. The length of her hull is 135 feet — 25 feet beam and 13 feet hold; drawing, when loaded, from seven and a half to 8 feet water. The gentlemen's cabin is below, and has 26 berths; and the ladies' cabin is on deck, with 18 berths — and are both elegantly furnished and well lighted — in this respect indeed, without disparagement to the other boats on the Lake, the William the Fourth has decidedly the advantage of them all. There is also a commodious and very comfortable forward cabin. The promenade deck extends over the whole vessel, in the manner of the Great Britain, and is finished in a style somewhat similar. The Engine is a low pressure, by Ward, of 100 horse power, with 8 feet stroke; and Captain Thorn (the commander of the boat) the engineer and Mr. Ward (who is on board) all say that she works well. She made the trip from Gananoque to Kingston in the unprecedented short space of one hour and three quarters — from Kingston to Cobourg, with a head wind, in ten hours, and from Port Hope to Gibralter Point, York, in five hours and a half. She sailed today at 10 o'clock for Hamilton, which place she will leave tonight for Niagara, and will return to York, on her way to prescott tomorrow.
Thge owners of the William the Fourth have it in contemplation to run her twice a week from Prescott to Hamilton, touching at all the intermediate ports on her way up and dpwn, and to carry passengers only. Captain Thorn informs us, however, that he thinks her trips will be arranged for once in five days, which she can perform with the utmost ease.
The number of Emigrants landed at Quebec, to the 14th. May inclusive, as reported in the Mercury, was 2, 453, viz: English, 1,760 — Irish, 673 -- Scotch, 20 = 2,453.
Nearly all the English Emigrants are from the southern tier of English Counties, Cornwall, Devon, Somerset, Dorset, Hants, Kent, &c. It will be seen that the Earl of Egremont has sent off a thousand of the poor of his parish, (Petworth in Sussex) at his own personal expense, and has presented £1,500 to the Secretary of the Canada Company, to be given to the poor people on their arrival in Canada.
This is a noble instance of benevolence on the part of his Lordship.
