METHODS OF FLAT PILING KILN TRUCKS 
A.—Cross piling.—The careful alignment of boards and of stickers and the adequate 
number of tiers of stickers in this illustration are admirable. Box piling, with the short 
lengths inside the outer tiers of full-length boards and staggered from end to end of the 
pile, however, is preferable tothe arrangement shown. Stringers stiff enough to support 
properly the outside stickers, or the arch stickering of Figure 13, give less degrade than 
deformed stringers, and the avoidance of overhanging ends of boards also reduce warping. 
B.—End piling.—Each tier of stickers is supported by a tie directly under it, all of 
the boards in each course-are of the same thickness, the narrow boards are grouped in 
pairs, and the sides and ends of the pile are uniform and vertical, all of which is highly 
desirable. On the other hand, placing the outer stickers at the extreme ends of the 
boards would reduce both warping and end checking, and uniformity of the vertical 
air channels through the pile would give faster and more even drying.
