 Fatal Explosion On 6OGrd the Steom-bOat Chief Justice MGsk0N.-For the first time since the introduction of steam boats, we have now to record fatal disaster on the North River, hy the bursting of boiler Last evening 4he Chief Justice MGrshalt, of Frog, and an old boat. but which had this winter been thoroughly overhaulej and re- paired-having landed passengers at New burg, was proceeding on her way to this city, when suddenly, and as will appear by a letter from the captain. unaccOuntably. the head of the boiler (which is of copper) blow out with a tremendous explosion; and the steam and boiling water rushing forth, scaldcd ten per- sons SO badly, that several of them are not expected to survive. And the boat itself, owing to one of the standing pipes being driv- en through the bottom, was of necessity run on a flat to prevent her sinking.

 a It appears there were on board 17S passen- gers; among whom as may be well imagined the consternation was very great. Happily, the accident occurred at an early hour in the evening and before the passengers had retired to their births; otherwise the disaster might have been much more fatal, for the steam spread itself in the cabin. The actual num- Der injured could not be ascertained. though no probable report rates it over ssrteen-the captain says ten. Several are said to have jumped overheard, and been taken up imme- diately, as the boat had just left the dock.

 Many of the passengers of the Chief Jus tice MarsknH came down this morning in the DeWitt Clinton.

 Annexed is the Captains letter:

 NEwBURe-s o'clock, Thursday. have the unpleasant duty to say, that shortly after leaving the dock for NewYork at this place, about o'clock, the whole front of our boiler blew out, with tremendous ex. pl0sion. Ten passengers are badly scaided

 three or four so much so that their lives are despaiFed of. The cause at present we know not. but can say that the steam was very low, and the boiler well supplied with water, at the time. The guage cocks were tried while landing. and the steam continually blowing off. As all is confusion, name the following persons as most injured :-NIr. Volant. engi- neer, badly; Jas. Williams.

 The explosion was. dreadful. happened to be standing in the most exposed situation. but received no injury of much consequence, and am doing all can for the comfort of the distressed. One of the stand pipes was tlriv- en through the bottom of the boat. and have hauled her on the flat below the dock. I am almost exhausted, and can say no more. ? IRA FORD.

 [The Daily Advertiser states that when the roll was called, it was found that none were missing-as it was at first apprehended some of the passengers might have been thrown or have jumped overheard.

 IHe Steamboat DisasteT.-Although we are yet left without names, or further particu- lars respecting the explosion of the Chief Justice Marshall, vet there has been des- tructiOn of life, more extensive and melan- choly than was anticipated yesterday. We learn this morning, that the sufferings of sEv- ENs of the victims were terminated by death yesterday, and is was believed that four oth- CTS would certainly die, and probably Ave- But one of the passengers is believed to have died. He was a workman at the Mattewan factory, and had just come on board. The Engineer of the boat is among the dead. and his body was brought to the city this morning. ny his brother. This accident has inspired the public with very general alarm. Last night. when the boat came along from Alba ny. only IA or IS passengers came off from Newburg, instead of from 30 to 60 as usuaL- ".

 It is hard telling where rests the blame for that there is blame somewhere, cannot be doubted: the art of governing steam is sim pie, a0d with scientific and careful engineer, Is almost impossible that accidents, of any serious import. can occur. That in this case, ignorance or carelessness is the cause Of this evs'nt, is plain and it is hoped and trusted that the most rigid Investigation may be had.-AkbGmy GGz.
