Sir,--I have had the satisfaction in other communications to report to you the excellent spirit evinced by the resident population of Canada in connection with the late Fenian attack on the Province. There has been in addition an exhibition of patriotism and devotion on the part of Canadians who happened to be domiciled at the time of the disturbance outside of the Province, which deserves, I think, special mention and praise. Immediately after the news of the inroad on the Province reached Chicago, sixty young Canadians who were resident there engaged in various employments gave up their situations and repaired by railroad to Canada to give their aid in defending the land of their birth. These young men have been formed into a Volunteer Company and are now doing duty at Toronto. I had also a communication from Her Majesty's Consul at New York to the effect that a large number of Canadians, resident there, were prepared to abandon their occupations and come to assist in the repulse of the invaders of Canada if I considered their services necessary. I informed Mr. Archibald by telegraph that I did not require their aid, but begged him to express to them my gratitude for the exhibition of their loyalty. Such conduct speaks for itself, and I would not weaken the effect of the bare relation of the facts by any attempts at eulogy on my part. I have, etc. (Signed) MONCK. The Right Hon. Edward Cardwell, Secretary of State. PROM THE IMPERIAL GOVERNMENT. The following General Order, contained in a letter communicated through the regular official channel to His Excellency the Governor-General and Commander-in-Chief (Right Hon. Viscount Monck), was duly promulgated through the Department of Militia of Canada:-- HORSE GUARDS, July 21st, 1866. The Under-Secretary of State for War:-- Sir,--With reference to the several reports which have been received from the General Officer Commanding in Canada relative to the Fenian movement in that Province, and to the measures taken by the colonists for repelling any Fenian attack, I am directed by the Field Marshal Commanding-in-Chief to request that you will acquaint the Secretary of State for War that His Royal Highness, having observed the alacrity, loyalty and zeal shown by the volunteers and militia forces of Canada in having come forward for the defence of the colony on the late trying occasion, in support of the troops, is very desirous of expressing to the force his full appreciation of their gallant and energetic behavior, and the very great gratification and satisfaction he has thereby experienced. And His Royal Highness trusts, therefore, that Lieut.-General Peel will see no objection to the necessary communication being made by him to the Colonial Office, with the view to His Royal Highness' sentiments, as above expressed, being made known through the proper channel to the volunteers and militia of Canada, lately employed against the Fenians. I am, etc., W. F. FOSTER.
