But perhaps the most interesting object of all was a sheet of parchment which lay stretched upon the table before the sitter, and which he had evidently been studying when the drowsiness of death seized him, and, sinking back in his chair, he had closed his eyes for ever. This parchment was, of course, stiff with the frost of centuries; but by exercising the utmost care the finders succeeded in conveying it intact to the _Flying Fish_, and in thawing it out, when it was found to be covered with a rude but vigorously drawn sketch or chart, representing with surprising accuracy of outline--but without much attention to scale--the whole of the channel between the west coast of Greenland and the east coast of America, and showing, at the top or northern margin, an irregular line _evidently intended to represent land_. And in the top left-hand corner of the chart was a square space marked off as a separate and distinct chart, the centre of which was occupied by an island, the southern coast-line of which corresponded in shape with the line drawn next the northern margin of the main or principal chart. Rudely drawn figures of the whale, narwhal, walrus, seal, and polar bear were sketched here and there upon the chart, as though to indicate spots where these animals had been seen by the author of the document; and on the island shown in the small subsidiary chart, great numbers of animals were drawn, among those represented being hares, foxes, deer, seals, and _elephants_, besides others which the travellers failed to identify. There was also a sketch of a ship--very similar in appearance to the craft from which the chart had been taken--represented as _sailing away from the island_. This particular sketch was the source of much speculation on the part of the quartette; Sir Reginald and the colonel being disposed to regard it as an insertion for the purpose merely of giving a more effective appearance to the chart, whilst the professor and Mildmay were of opinion that it was intended to convey an intimation that the mysterious island had actually been visited.
