An explosion of a rotary rag-boiler, receiving steamfrom steam-boilers at a distance, which took place atPaterson, N. J., wrecked the mill, destroyed a part ofan adjacent establishment, and caused serious loss oflife and property. The disaster was due to the weak-ening of the boiler by corrosion, but, notwithstandingits reduced strength, the shock of the explosion wasfelt, and was heard, throughout the city, and heavyplate-glass windows were broken at a considerable dis-tance from the scene of the ac
