Fire Balloons--The reprehensible practice of sending up fire balloons, is again becoming fashionable, and if persisted in, we may look for a conflagration speedily. It seems that the thing is done every night lately, in one or more sections of the city. On Monday evening one fell upon a house in the upper part of the city and set fire to the roof, the timely discovery of which probably alone, prevented the destruction of the dwelling. If the parties to these "infernal machines" can possibly be detected, it is due to them that they should have the full administration of the law.
