Even if candles approved by health authorities are used, it is best 

 to use twice as many of them as directed. 



Fumigating with Sulphur Candles. The preparation of the room 

 for fumigation is exactly the same as for fumigating with formalde- 

 hyde. For a room 12X12X10, six of the pound candles would be 

 needed, no matter what the directions accompanying the candles 

 may call for. Put them in pans on the table, not on the floor, in 

 the center of the room, fill the water jackets two thirds full, light 

 the candles, leave the room promptly, and seal the exit door. Leave 

 the room sealed for from 12 to 24 hours. 



The advantage of sulphur fumigation over formaldehyde fumiga- 

 tion is that it kills all insects as well as germs and thus prevents 

 insects carrying the disease. 



The disadvantage is that the fumes of sulphur tend to bleach 

 and otherwise to impair all kinds of' fabrics, and are apt to injure 

 brass, copper, steel, or gilt work. 



NOTE. An excellent gum for use in sealing the room with news- 

 paper strips is powdered gum tragacanth. Soak two teaspoonfuls 

 of powdered gum tragacanth in one pint of cold water for an hour. 

 Then place the vessel containing the mixture in a pan of boiling water 

 and stir until the gum is dissolved. This seals effectively, washes off 

 easily, and will not stain or discolor woodwork at all. 







PROJECT XLIX. How to Prevent Dampness in Cellars and 

 Dark Closets, page 444 



Since dampness and darkness are favorable to the growth of 

 bacteria and molds, and furnish inviting conditions for waterbugs, 

 roaches, and other disagreeable insects, modern houses are built 

 as nearly damp-proof and as free from dark corners as possible. 

 In many old-fashioned or ill-constructed houses, there are damp 

 and dark closets and cellar-rooms. To the unpleasantness and 

 unhealthfulness of such corners is added the loss occasioned by 

 rust and mildew. 



Permanent removal of these conditions by whatever building 

 alterations are necessary is the most satisfactory remedy, and
