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. Carelessness with matches during the year . 1915 resulted in no less than 1,314 fires, as against’l,24B such fires in 1914. Ordinances have been put into effect in New York with a view to lessening e tho number of fires arising out of care- j, lossness. REMOVING RUST FROM f NICKEL. First smear the rusted place with grease and rub it well in; this in itself frequently will remove a great deal of ' f tho rust.’ Allow the grease to remain 1 s . for several hours, and then remove it ! with a rag which has been dipped' in ! ammonia. This usually will remove all ,r traces of tho rust. If, however, a 0 " stubborn spot or two remains, wipe it with a little dilute hydrochloric acid. The acid should be used very quickly p and with care, otherwise it will remove s tho nickel as well as tho rust. When all the rust has disappeared, wash the place where the treatment was applied j, thoroughly with clean water, and then p use a metal polish. , i NEW INDUSTRY. j" Talc or soapstone is now being shipped o regularly to Great Britain from South s Africa, a development in the industry which has taken place since the beginning of the European war. The South f. African tale is being supplied from tho s Barberton district, but it is also found ■ in Rhodesia. The British and South African Export Gazette states that it:? discovery is almost a romance, and p; y; < a tribute (o the patience and persever- ; anee of the man who was solely re- >. i sponsible for it. For over six years, states the journal previously men | Honed, the man continued his prospect- i j ing work, often in the face of ridicule, j 1 aiid more frequently of calumny. Thus
