Before making the proposal, Parry had given the subject careful consideration. He mentions that Captain Lutwidge, the associate of Captain Phipps in the expedition towards the North Pole in 1773, describes the ice north of Spitzbergen to the distance of ten or twelve leagues to have the appearance of “one continued plain of smooth unbroken ice, bounded only by the horizon.” The testimony of Mr. Scoresby, Jun., “a close and intelligent observer of Nature in these regions,” was also found to agree with that given by Lutwidge. “I once saw,” says he, “a field that was so free from either fissure or hummock, that I imagine, had it been free from snow, a coach might have been driven many leagues over it in a direct line, without obstruction or danger.” In addition to these, experienced whalers, whom Parry consulted as to the nature of the ice, agreed that it was highly favourable for the purpose of his expedition. An important factor in determining Parry to make the proposal was the fact that Franklin had drawn up a plan for making the attempt on the same lines. For the journey over the ice, two boats were constructed having great flatness of floor, with the extreme breadth carried well forward and aft, and possessing the utmost buoyancy, as well as capacity for stowage. Their length was 20 feet, and their extreme breadth 7 feet. The timbers were made of tough ash and hickory, 1 inch by half an inch square, and a foot apart, with a “half-timber” of smaller size between each two. On the outside of the frame thus formed was laid a covering of Mackintosh’s waterproof canvas, the outer part being coated with tar. Over this was placed a plank of fir, 3/16 of an inch thick; then a sheet of stout felt; and over all, an oak plank of the same thickness as the fir; the whole of these being firmly and closely secured to the timbers by iron screws applied from without. “On each side of the keel, and projecting considerably below it, was attached a strong ‘runner’ shod with smooth steel, in the manner of a sledge, upon which the boat entirely rested while upon the ice; and to afford some additional chance of making progress on hard and level fields, we also applied to each boat two wheels, of 5 feet diameter, and a small one abaft, having a swivel for steering by, like that of a Bath chair; but these, owing to the irregularities of the ice, did not prove of any service, and were subsequently relinquished. A ‘span’ of hide-rope was attached to the fore part of the runners, and to this were affixed two strong ropes of horse-hair, for dragging the boat; each individual being furnished with a broad leathern shoulder-belt, which could readily be fastened to or detached from the drag-ropes.” The boats weighed 1539 lb. and 1542 lb. respectively. Two officers and twelve men were selected for each boat’s crew. The provisions consisted of biscuit, sweetened cocoa-powder, and pemmican. The process of making the latter consisted in drying large
