The gentleman from Massachusetts says it is true that a considerable alarm was excited in England when the news of the embargo arrived there; that they had been led to believe, from their writers and speakers, that a discontinuance of their intercourse with this country would be productive of most injurious consequences; but that they were now convinced that all their writers and statesmen were mistaken, and that she can suffer a discontinuance of intercourse without being convulsed or suffering at all. To believe this requires a considerable portion of credulity, especially when the most intelligent men affirm to the contrary. In the last of March or the first of April last, we find, on an examination of merchants at the Bar of the British House of Commons, that the most positive injury must result from a continuance of non-intercourse. It is not possible that our merchants on this side of the water, however intelligent they may be, can be as well acquainted with the interests of Great Britain as her most intelligent merchants. This alarm, however, the gentleman has told us, continued through the spring and dissipated in the summer. It is very easy to discover the cause of the dissipation of this alarm. It was not because the loss of intercourse was not calculated to produce an effect, but it proceeded from an adventitious cause, which could not have been anticipated--the revolution in Spain; and there is no intelligent man who will not acknowledge its injurious effects on our concerns. No sooner did the British Ministers see a probability that the struggle between the Spanish patriots and France would be maintained, than they conceived hopes that they might find other supplies; and then they thought they might give to the people an impulse by interesting the nation in the affairs of Spain, which would render lighter the effects of our embargo. This is the cause of the change in Mr. Canning's language; for every gentleman in the House knows that a very material change took place in it in the latter part of the summer. If then the embargo has not produced the effects calculated from it, we have every reason to believe that its failure to produce these effects has been connected with causes wholly adventitious, and which may give way if the nation adheres to the measure. If, however, there be any probability that these causes will be continued for a long time, we ought to abandon it. I am not in favor of continuing any measure of this kind, except there be a probability of its producing some effect on those who make it necessary for us to exercise this act of self-denial. When I first saw the account of the revolution in Spain, my fears were excited lest it should produce the effect which it has done. As soon as I saw the stand made by the Spanish patriots, I was apprehensive that it might buoy up the British nation under the sufferings arising from the effects of their iniquitous orders,
