The Jaokson Patriot of the ,'iOth uit. has the following : Yesterday morning at about fwe o'clock two convicts at the prison named respectively Williaui A. Waterman and Henry Murrill, alian Henry Jones, succeeled in effecting their escape, and up to last night had not been recaptured. Waterman is thirty-seven years of age, and is from Ottawa county, having been genteneed lor burglary at Holland. Murrill is nineteen years of age, and is from Grand Rapids, where he committed larceny by stealing a coat. A reward of $100 is offered. tor their arrest, by Agent Morris. The Murrill mentioned above is the same boy who stole the billiard baila from a saloon in this city and sold them in Lansing a inonth before his arrest in Grand Rapids. The particulars of the escape, as furnished us at the prison, are as follows : A party of men employod in the kitchen are unlocked at four o'olock and another party at five o'clock, to which latter party the escaped convicts belonged. There was no guard with the latter party, but there was one with the former, who was at the time in the kitchen, but who, it is said, is a new hand and not up to all the dodges of the men. The two men who escaped went to the diuing-rooin, which is situated on the north side, then dodgod off and carne back, evidently having a plan of escape thoroughly prepared. They climbed up on the roof of the new dining-room - just in the same manneras the three who attempted their escape a few days ago did - then on to the roof of the west wing, then down to the west wall, where they had the advantage of the steps used by the guard to descend to the ground. At that early hour the guard had not mounted the walls, their time for doing so being ten minutes to six in the morning, and consequently when once on the walls the escape of the two men was comparatively easy. Another thing in their favor was the darkness of the morning, only streaks of daylight being visible at the hour they escaped. They were traced to the railroad by their tracks in the mud, but when once there they had evidently walked on the ties, thus concealing further traces. The supposition is that they were hiding in some place not far from the city all yesterday, jonsidering it only safe to travel in their prison garb In the darkness oí night.
