TIMBER STORAGE IN THE EASTERN AND SOUTHERN STATES. 23 



retail yards where it is the custom to dispose of the stock within 

 very short periods, say, two or three months. In some of the 

 northern retail yards along the Atlantic coast, where southern pine 

 comes in by boat in a comparatively green condition, this prac- 

 tice often leads to severe fungous infections throughout entire 

 piles. This infection undoubtedly gets a good start in the hold 

 of the vessel during transit and propagates further when close 

 piled in congested lumberyards. Such a pile of diseased pine is

It is not the intention in the present bulletin to enter into a dis- 

 cussion of detailed methods of stacking lumber. The primary con- 

 cern, from the standpoint of sanitation, is to dry the lumber as 

 rapidly as possible and maintain it in this condition. However, 

 other considerations, such as checking and warping, must be taken 

 into account in many instances. The humidity or dryness of the 

 climate will be of great weight in determining the proper amount 

 of ventilation to give the best results from all standpoints.
