The Ericsson, or Hot Air ship is now lying at her old berth at Green Point, Williams-burgh. It will no doubt be interesting to our readers to know the present opinion of some of our papers about it, and what she is lying at that place for. " The ship Ericsson, which arrived here on Monday, left the Capes on Friday afternoon, and stopped four or five hours on the way.— The confidence of the owners, it is said, was greatly increased in the caloric engine by the late trip. She went to Washington before she was complete in order to be there before the adjournment of Congress. She will now go to the shipyard at Williamsburgh, and remain about a month undergoing the finishing opera tions. The object thus far having been to see Lhow well the machinery will work; it is sup posed that the test of speed will be an objec on her next appearance. It is claimed by some of the admirers of the new motive pow-er, that when the maximum ol speed is reach ed in the caloric engine, the steamers will not exceed them in rapidity by more than a knot an hour."—[Tribune of the 16th. The caloric ship Ericsson, which returned to this port on Monday, is soon to leave for London, from whence it is intended to send her to Australia. Her recent trip to the South has established the partial success of the new principle, at the same time that it has sug gested some important improvements, the in troduction of which it is expected will mate rially augment her rate of speed. Her ap pearance in the Thames will create quite a sensation among the Britishers."—[New York Herald of the 16th. The Herald of the 24th Feb. said, about the Ericsson, " the caloric experiment has been signally successful," it now says partially suc cessful. The " Tribune makes excuses for the bad performance of the Ericsson, by saying she went to Washington before she was complete. Her speed on her trip home, was about 4 miles per hour. After her last trip down New York Bay, she was laid up at Green Point for a month getting some repairs made, and now after her trip to Washington she is to be laid up for another month's repairs.— These are not our reports but those of the pa pers who have hitherto so highly praised the Ericsson. Before the hot air ship will be able to compete with a steamship, she will have to get in new boilers and engines, use more coal, and keep a good supply of water in the boilers. Those ignorant men who have talked about her running faster if she had larger engines, would look blank if told she could not run as fast as the Arctic if she was stowed with hot air engines from top to bot tom, but so it is. What excuses are now made for the slow speed of this ship by the very papers who shouted and bayed a few weeks ago at James Watt, Robert Fulton, and all the inventors that ever lived, and all the steamboats in creation. The " Tribune " at last gives in and admits that after she has attained to her great est speed, steamships will still run faster, does this look as it " the days of steam were num bered." Since we last said anything on the question of hot air as a motive power, the subject was discussed two nights in the London Institute of Civil Engineers, and a paper was read on i1 by B. Cheaverton. Some of the most emi nent men in the country, such as Stevenson Rennie, Meadows, Sir Geo. Cayly, &c , wer present. Drawings of the Ericsson's engines were presented and explained. They all condemned the regenerator as a fallacy, and the conclusion arrived at was, that with th amount of coal burned she made slower pro gress than a steamer would. We have made but one or two commentary remarks; there is much that we could say but we do not wish to take up too much rooir discussing one subject. We have presented ; great deal of information respecting the Erics son, because this ship has created a great sen sation throughout the whole country, and ou: readers desire to have all the impartial infor mation they can get about it. We will stil present from time to time such information as may be new, instructive, and interesting abou hot air as a motive power. We conclude bj statingthat the " American Journal of Sciena and Art" for March, after descibing thi " Ericsson's" engines says, " we do not at pre sent undertake to discuss the probable succesi or iailure of this important enterprise," an thus the great gun fires neither a blank no: ball cartridge, the gunner evidently exhibit ing either a fear or a want of ability to do so
