BULLETIN 510, U. S. DEPARTMENT OF AGRICULTURE. 



A broad survey of the lumber industry shows some instances where 



absolutely no atten- 

 tion is given to yard 

 sanitation (fig. 7) and 

 also a few other in- 

 stances w here the 

 yards are sodded and 

 handled like a well- 

 kept lawn (fig. 8). 

 The great majority, 

 however, fall between 

 these extremes. As a 

 rule, grass and weeds 

 are kept under fairly 

 good control either by 

 mowing or by pastur- 

 ing. In most in- 

 stances some rotting 

 debris is scattered 

 about. The factor of 

 location often plays 

 an important part in 

 sanitation, for on 

 swampy land the les- 

 sened fire danger 

 tends to encourage 

 carelessness.

Fig. 7. — A small, very insanitary mill in Louisiana. 

 The conditions at this mill are a disgrace to the lumber 

 industry. Note the rotten, dilapidated tramway, the 

 lumber stacks placed within 2 to 4 inches of the 

 ground, and the debris scattered about and breeding 

 infection. 



Any decaying tim- 

 ber which has been 

 alloAved to accumu- 

 late about the yards 

 should be collected 

 and burned. The 

 mere carting of such 

 debris to a conven- 

 ient near-by pile (PI. 

 Ill, fig. 1 ; text fig. 9) 

 is not sufficient, for 

 the fungi will con- 

 tinue to thrive in 

 such material for 

 long periods and to 

 produce fruit bodies 

 which will liberate 

 millions upon mil- 

 lions of spores into

 mill in Louisiana. Practically all the lumber is run 

 through thf dry kiln and stored in largo sheds, thus 

 eliminating the problem of storage rots.
