y S' (1 1, CIGARETTES AND FIRES. tl During- the past year it is reported ® that there were 1,306 fires caused by cigars and cigarettes carelessly thrown away, in New York alone. The average ' loss per fire during 1914 was a little F over 569 dollars, and. if each fire re- j suiting from cigars and cigarettes and ~ other similar causes should equal this 1 sum, tho total loss duo to carelessness . would bo about 743,114 dollars.
