Mr. Ashurst, father of the [late] solicitor to the Post Office, having been requested to act as solicitor to the committee, went promptly to work; and though by choice he acted gratuitously, he laboured with as much ardour as if important personal interests were involved in the issue. No less earnestness was shown by Mr. Henry Cole,[152] who had been engaged to aid in the work. He was the author of almost innumerable devices, by which, in his indefatigable ingenuity, he contrived to draw public attention to the proposed measure. He once passed through the Post Office, and afterwards exhibited in fac-simile to the public eye (the originals being previously shown in Parliament), two letters, so arranged as to display, in the clearest light, the absurdity of the existing rule of charge. Of these, one nearly as light as a feather, and almost small enough to require a pair of forceps for its handling, quite a letter for Lilliput, but containing an enclosure, bore double postage; while the other, weighing nearly an ounce, eight inches broad, and more than a foot long, when folded a very creditable letter for Brobdingnag, but all written on one sheet, had its postage single. Meanwhile the Parliamentary Committee, appointed on the motion of Mr. Wallace, began its sittings. Mr. Wallace, being appointed chairman, thenceforth concentrated his indefatigable efforts upon its work; and his labour during the whole session—his duties being by no means confined to the formal sittings—was most severe. The committee sat no less than sixty-three days. They examined “the Postmaster-General, the secretaries and the solicitors of the three Post Offices of England, Ireland, and Scotland, and other officers of the Post Office department; obtained many important returns from the Post Office, most of which they directed to be prepared expressly for their use; and also examined the chairman, secretary, and solicitor of the Board of Stamps and Taxes, Mr. Rowland Hill, and eighty-three other witnesses, of various occupations, professions, and trades, from various parts of the kingdom; in the selection of which they were much assisted by an association of bankers and merchants in London, formed expressly to aid the committee in the prosecution of their inquiry.”[153] This association was the committee formed by Mr. Moffatt. The committee wisely directed its attention chiefly to the question of inland postage, which indeed offered abundant matter for investigation.
