Management. 



(8) The reservoir should be filled with oil before the lamp 

 is lit. 



(9) The lamp should be kept thoroughly clean, all oil should 

 be carefully wiped off, and all charred wick and dirt removed 

 before lighting. 



(10) When first lit the wick should be partially turned down, 

 and then gradually raised. 



(11) The wick should not be left turned down, as there is then 

 a greater liability to explosion in lamps of unsafe construction. 



(12) Lamps which have no extinguishing apparatus should be 

 put out as follows : — The wick should be turned down until 

 there is only a small flickering flame, and a sharp puff of breath 

 should then be sent across the top ot the chimney, but not 

 down it. 



(13) Cans or bottles used for oil should be free from water 

 and dirt, and should be kept thoroughly closed. 



Note. — These suggestions apply to ordinary petroleum or 

 paraffin lamps such as are generally used, and not to benzoline 

 or spirit lamps.
