in order to destroy the eggs. It may be necessary to devise some means of 

 sterilizing the mattresses with steam or hot air. Fumigation with sulphur 

 will kill the adult bedbug but will not affect the eggs. 



Roaches. 



Roaches frequently pass from toilets, sewers and drain pipes to refresh- 

 ment stands, kitchens and dining rooms in restaurants and camps, and may 

 therefore constitute a menace to health. The prevention of roaches can be 

 accomplished by the elimination of cracks, crevices and dark corners in 

 kitchens and dining rooms and by keeping all the supplies in roach-proof 

 containers. Fumigation by sulphur will kill the roaches reached by the 

 gas, but the best way to eradicate them is by the use of roach powder, 

 consisting of sodium fluoride mixed with meal or flour. This powder is 

 dusted in corners, closets, drawers and dark crevices. 



SANITARY CARE OF AREAS AND FACILITIES OF VARIOUS KINDS 

 Camp Grounds. 



Cleanliness is so intimately related to sanitation that a clean camp 

 will, as a general rule, be sanitary. Every camp director wishes to have 

 his camp present an attractive and pleasing appearance, and this cannot be 

 done unless the grounds are clean and sanitary. To this end all rubbish 

 should be removed at once. Such places as the rear of kitchens and dining 

 rooms should be carefully watched. As a rule "out of sight out of mind" 

 applies only too often to dirt and rubbish. All low spots, walks, roads and 

 paths should be drained by suitable and well-kept ditches or by under- 

 ground tile. In tent camps every tent should have a trench on all sides 

 to carry off storm water, and prevent the formation of mud holes. Rank 

 vegetation and long grass should be kept down. 



Picnic Grounds. 



Picnic grounds, unless kept under very close supervision, will likely very 

 soon become covered with papers, fruit skins, pieces of food and other 

 debris carried in by the picnickers. Every picnic ground should have several 

 commodious receptacles into which the remains of eating can be thrown. 

 It would be well if one of these receptacles were water-tight, into which 

 could be thrown stale coffee, dishwater and other liquids resulting from 

 the picnic dinner or supper. Attractive signs, posted at conspicuous places 

 about the grounds, giving instructions to picnickers where to deposit refuse, 

 may help some in keeping the ground better policed. Some park executives 

 who handle their picnic ground under a permit system require a deposit 

 of from one dollar to five dollars from the group as a guarantee that the 

 grounds will be left in as good condition as they were found. If the pic- 

 nickers police the ground well the deposit is returned. If not, the deposit
