 those lighted by voyageurs, and these must occupy only

 utterly extinguished before being left. Heads of parties 

 of voyageurs must be made responsible, under pain of 

 fine, for the negligence of their men. Eailroad com- 

 panies must be compelled to put wire-gauze bonnets on 

 their locomotives, to prevent the sparks from the chim- 

 neys from setting fire to the bush ; and the companies, as 

 well as the direct author of the mischief, be made answer- 

 able for any damage done. And, lastly, to arrest a con- 

 flagration already started, the forest-guardians must be 

 authorised to hire, when necessary, a force equal to its 

 suppression ; to make ditches, and to fill them with water 

 when practicable, to extinguish the fire by throwing 

 earth upon it, to cut down the neighbouring trees, and 

 to start an opposing fire when it is found advantageous 

 to do so. The employment of some or all of these 

 remedies cannot fail to produce good results.

 out hundreds and thousands of trees. It is a day of 

 popular rejoicing, and has become part of the national 

 life-
