swell, but the experiment yielded some unexpected results. Large-size 

 all-cleft wood swells more than small round wood — 1 6-inch wood swells 

 more than the 12-inch. The reason is that the smaller the pieces into 

 which the wood is cut the more clo.sely it packs when thrown into the 

 bin. The mixed round and cleft wood gave very uniform results, the 

 average of 15 cords in the case of 12-inch wood being 145 cubic feet 

 and in the case of 16-inch 160 cubic feet. The amount of actual solid 

 wood to be obtained by this method of measurement is bound to be 

 much more uniform than that obtained in the stacked cord, so that any 

 deviation from these averages is more due to the irregularity of the 

 solid contents of the stacked cord than to the hazards of loose piling in 

 a bin. In order to determine whether the size of bin made any differ- 

 ence to the cubic contents, one was constructed which was 8 feet on a 

 side instead of 5. In the case of 12-inch wood this gave results iden- 

 tical with the 5-foot bin. In the case of 16-inch, the contents are a 

 little smaller, but not enough to be a serious matter. A bin which was 

 only 2y2 feet wide instead of 5 feet was then constructed, and the cubic 

 contents of a cord became 184 cubic feet instead of 145 feet, the aver- 

 age. It is apparent, then, that for the measurement of thrown wood 

 the bin must not be less than 4 or 5 feet in its least dimension. It can 

 be larger, but as a practical matter a bin of large surface dimensions is 

 not recommended, because a slight error in measuring the height of the 

 wood means a cfmsiderable error in the cubic contents thereof. It ap- 

 l)ears that a man who sells considerable cpiantities of short wood should 

 be required to provide himself with a bin 5 feet wide. 8 feet long, and 

 4 feet deep. This bin. level full, with 16-inch wood, will contain i cord. 

 1 f filled to a depth of 3 feet 8 inches with t 2-inch wood, it will contain 

 1 cord. A t'-eniovable partition placed across the middle will make it 

 ])ossible to measure iialf cords. With an arrangement (^f this kind it 

 will be possible for the dealer to keep on hand a large stock of short 

 wood, and not be obliged to go to a pile of 4-foot wood and measure 

 out each iiuli\iilual order and then saw it u]). as is the custom at 

 present.
