Some years ago, upwards of 100,000_l._ were lost, through the partner of a large establishment lighting gas with a piece of paper, which he threw away, and thus set fire to the premises, although it was a strict rule in the place that gas should only be lighted with tapers, which were provided for that purpose. In one department of a great public institution, it was, and is still, a rule that only covered lights should be carried about, and for that purpose four lanterns were provided; yet, on inquiry some time back, it was found that only one was entire, the other three being broken--one having lost two sides and the top; still they were all used as covered lights. The opportunities for inattention to fires and lights are so various, that it is impossible to notice the whole. One of the prevailing causes of fire is to be traced to persons locking their doors, and leaving their houses to the care of children. I believe one-half of the children whose deaths are occasioned by accident suffer from this cause alone: indeed, almost every week the newspapers contain some melancholy confirmation of what I have here stated. Intoxication is also a disgraceful and frequent cause of fire. The number of persons burned to death in this way is really incredible. It is true that it does not always happen that a fire takes place in the house, in either of the above cases, although the unfortunate beings whose clothes take fire, rarely escape with their lives; but the danger to the neighbourhood is at all times considerable, if persons in a state of inebriety are left in a house alone. When there is reason to apprehend that any member of a family will come home at night in that state, some one should always be appointed to receive him, and on no account to leave him till he is put to bed, and the light extinguished. I do not mean to say that people must be actually drunk before danger is to be apprehended from them. Indeed, a very slight degree of inebriety is dangerous, as it always tends to blunt the perception, and to make a person careless and indifferent. I may also add, that no inconsiderable number of fires are occasioned by the thoughtless practice of throwing spirits into the fire. The dresses of females taking fire adds very much to the list of lives lost by fire, if it does not exceed all the other causes put together. Another very general cause of fire is that of approaching with lighted candles too near bed or window curtains; these, being generally quite dry, are, from the way in which they are hung, easily set on fire, and, as the flames ascend rapidly, when once touched, they are in a blaze in a moment.
