Warlike Preparations
Troops Under Orders for Canada
Letter from Gen. Scott.

       By the steamship Jura, at Portland from Liverpool and Londonderry on the 6st inst. (whose arrival we announced yesterday), the following has been received:
       The excitement relative to the Trent affair continued abated (sic). The stock market was more heavy and unsettled than ever.
       The United States Consul at Paris had communicated to the French papers a letter from General Scott, in which he declared there is no truth in the report that the Cabinet had ordered a seizure of the Southern commissioners, even under the protection of a neutral flag. He was quite ignorant of the decision of his Government, but says it is necessary to preserve good relations between America and England; and England, he hopes, will agree on a solution of the question whether the prisoners were contraband or not. If they were agents of the rebels, be says it will be difficult to convince even impartial minds that they were less contraband of war than rebel soldiers or cannon. In conclusion, General Scott expresses his conviction that a war between America and England cannot take place without more serious provocation that at present given.
       The London Star thinks that Gen. Scott's letter will receive a hearty response in England as a message of peace.
       The Times says that Gen. Scott, like his countrymen, is rather inclined to disavow the conception of the outrage than to repudiate it, now that it has been done.
       It is reported that rebel and federal privateers are cruising at the entrance of the English channel.
       It is said that the Admiralty have ordered two ships to proceed immediately to the West Indies to act as convoy to mail steamers.
