This was a grand opportunity for pushing their fortunes in that quarter, which the Americans knew well how to profit by. In reality, the whole foreign trade was for a time in jeopardy; but the Americans profited precisely in proportion to the increase of our difficulties, and their trade increased exactly as ours declined. The moment was an advantageous one for proving to the Chinese that Americans were not Englishmen; although they cleverly made them understand that they _had been_ so once, but at last had conquered for themselves a name, a flag, and a nation. It has been said that, at a later period, an American merchant had more than one interview with Lin, in which various suggestions were made as to the measures to be adopted; but, whether they were of a favourable or unfavourable nature to English interests, it is impossible to say with confidence. The results of the conference were kept very secret. Having secured all the foreigners within his grasp, Lin's next step was to withdraw all the native servants from the factories, and to forbid the sale of provisions to foreigners in any shape. Armed men were posted on every side, to prevent any one from attempting to escape, while the river was blockaded, and all the foreign boats which could be found were drawn up high and dry on shore, or else destroyed. In the meantime, however, no provisions were supplied by Lin himself; consequently, the foreign prisoners were in a worse plight, in that respect, than the actual malefactors in the cells of the public prisons of the town; and his object was evidently to _starve_ them into compliance with his wishes, if, indeed, he knew himself what the full extent of his wishes really was. Captain Elliot was now called upon to deliver up _all_ the opium, wherever it might be found. And yet it was clear enough that Captain Elliot could not possibly know _where_ all the opium was, or how much it might be; and, having already agreed to the demand for, first, one thousand, and then four thousand chests, it would clearly be necessary to stipulate some quantity as a satisfactory equivalent for all.
