The tclegrnph infernis us that Gen.Hooker rutirexi from the Arftiy of the Potomaff, and' that Geueral GeorgeC. Mende; well known to most of our citizeos, has suecoeded to bis position. Gen. Moade was bom in Spain, his father at tho time boing in the einploy of the Government as Consul, we beüeve, at Cadiz. He was appointed as a Cadet at West Point in September, 1831, and graduated from that school on the lst of July, 1835, and was brevetted at once as secoud lieutenant, and1 assigned to tlie third artillery for service. Like many of the ablest of our yourg offiWs, he resigned Lis position in the army in 18H0. In 1842 ho returr.ed to the regular servi4e aud was appointed as Second Licutsürant of the Topographieal engineers, for which he was eminently fittcd. He distinguished himsslf in the battle of Palo Alto, under Gen. Taylor, and was af terwards brevattcd and promoted for his gallant conduct in the severe conflict at Monterey in September, 1856' As he was attaehed to the army undsr General Taylor he had co opportunity to particípate iu the great battles fought by Gen. Scott and his army frota Vera Ci'uz to the capital of Mexico. We have ofteo heard it stated, and have no doubt of its truth, that when Jeiferson Davis first made the selection of officers froin the army to visit the Crimea, on account of bis services and military knowlütlge, was placed at tho head of the Comuiission, but it was found that he could not be spared from hia then present duties, and General McClellan was appointed. - Whether this is true or not, we know that Gen. Meada among his associates in the army has always borne a very high reputation as an oflicer. Foqgseveral years prior to the commencement of the war, he was in charge of the Lake Coast Survey, and psided in this city. In this position, as in every other he ever occupied, he displayed qualities which won for him the commendation and praiBe of the department, and tho estcem and adiniration of all who were so fortúnate as to make his acquaiutance. On the 31st of August, 1861, he was appointed Brigadier General of the army of volunteera, and from that date until the present he has been connected with the Army of the Potomac. In the battle of Chancellorsville he commanded the Fifth Army Corps with great abihty. Frouihhiu past esperience, from his known bravery, fiom hia thorough knowledge, we are rejoieed to aay, tbat so far as we can judge, the Army of the Pototnac has a commander in Major General Meade every way competent to handle it with ability, and, we trust, with success. While we entertain tbese views, and congratúlate the country on the cbange, it must be remembered that tho administration at Washington has made it at a time when it vvill try General Meade's capacity to the utmost. The change of a commander in the presence of the enemy is proof that the government was wrong before, and it can hardly be expected that Gen. Meade can at once inspire his soldiers with the enthusiasm and courage which proceeds from personal acquaintance and iutercourse with his meo. With the same opportunity we have full confidence that he will rival McClellan in tbia respect, but he must fight his first great. battle before he has any such opportunity, and it reraaius to be geen whether he can win victory against such circumstanco. If ho caD, it will be still more to his credit.
