Nor does it appear that the nefarious practices of these Lightermen have been confined to West Indian produce alone. Their criminal designs were directed to almost every species of merchandize placed under their charge; and the tricks and devices to which they were accustomed to resort, clearly evinced that their plans for obtaining pillage had long been systematized, and that they seldom permitted any opportunity whereby they could profit by making free with property under their charge to escape their attention. As a proof that this assertion is well grounded, the following authenticated case, among others which could be detailed, is stated as an instance of the extreme rapacity of this class of men.--A Canada merchant, who had been accustomed to ship quantities of oil annually to the London market, finding (as indeed almost every merchant experiences) a constant and uniform deficiency in the quantity landed, greatly exceeding what could arise from common leakage, which his correspondents were quite unable to explain; having occasion to visit London, was resolved to see his cargo landed with his own eyes; so as, if possible, to develope a mystery heretofore inexplicable, and by which he had regularly lost a considerable sum for several years. Determined therefore to look sharp after his property, he was in attendance at the wharf in anxious expectation of a lighter which had been laden with his oil on the preceding day; and which, for reasons that he could not comprehend, did not get up for many hours after the usual time. On her arrival at the wharf, the proprietor was confounded to find the whole of his casks stowed in the lighter with their bungs downwards. Being convinced that this was the effect of design, he began now to discover one of the causes at least, of the great losses he had sustained; he therefore attended the discharge of the lighter until the whole of the casks were removed, when he perceived a great quantity of oil leaked out, and in the hold of the vessel, which the Lightermen had the effrontery to insist was their perquisite. The proprietor ordered casks to be brought, and filled no less than nine of them with the oil that had thus leaked out. He then ordered the ceiling of the lighter to be pulled up, and found between her timbers as much as filled five casks more; thus recovering from a single lighter-load of his property, no less than fourteen casks of oil, that, but for his attendance, would have been appropriated to the use of the Lightermen; who, after attempting to rob him of so valuable a property, complained very bitterly of his ill usage in taking it from them.
