He immediately saw that it was a sheet of paper about the size of foolscap, but somewhat squarer, of a bluish tint; it was provided free of cost to the frequenters of the sailors' reading-room at "The Swan." He well knew the paper, for many a letter written upon it had he received. It was of a convenient size for those who used it, as first of all it was ruled on one side, which enabled a man to steer a straight course with his pen. The page was likewise so large as to enable a man to write big, and few who used it could write small. It also supplied plenty of space for erasures, whether of expression or spelling, and this was useful. When folded into four and sealed or wafered, the sheet became a letter which needed but the address to qualify it for the post. In the case of the sheet Mr Greyquill held, it had been folded to resemble a letter, but it had not been made one; it bore no address, and the communication started at once without the prefatorial "Dear sir," or the like, and it closed without signature or initials. But Mr Greyquill immediately saw that the handwriting in pencil was Mr Lawrence's, and that the document must have fallen from that gentleman's pocket just now when they parted. We have seen that the frame which bounded Mr Greyquill's portrait of honour was large. Most men recognising the handwriting would have denied themselves the right of reading this letter, because they had found it lying in a public roadway, for two reasons: the handwriting was known to them, and the recent presence of the writer where that letter was found would have identified it as its owner's business in no wise to be intruded on by a man of honour. But this sort of argument did not fall within the frame of Mr Greyquill's picture of integrity. It was a letter lying ready for anybody's hand in a public way; next, it was not addressed; third, it was not signed; and fourth, though the contents were apparently in Mr Lawrence's handwriting, yet some people did write, as Greyquill knew, so wonderfully alike that there was no reason to conclude without strong internal evidence that the letter Mr Greyquill held was written by Mr Lawrence. Whatever else it was, it was certainly a draft roughly pencilled of a letter that had been copied in ink and no doubt despatched. Here and there was an erasure in ink, which proved that it had been copied in ink and corrected in certain places by the pen that was transcribing it. He had not proceeded far when his eyebrows, which, as we have heard, inimitably expressed the aspect of two white mice, arched their backs to an extraordinary degree as though in imitation of a cat when enraged; his mouth took on the posture of a whistle; with his eyes rooted to the sheet he stopped and scratched his head until he nearly tumbled his hat into the road.
