NoTK. — In the ".starred" percentage ou y. pine "M," the cut was made 1 foot from previous one on 

 account of knot. Piuce.s " IST " and " O " have 10 feet yec to be cut. The diagrams were made on per-

Out door seasoning depends a great deal on tlie character of the 

 weather during the year, that is, as to an early or late spring or fall, 

 hot or cold summer months, or severe winter, etc., but during the ex- 

 periments it may be considered to have been average Illinois weather. 



The result of this series of experiments shows that the month during 

 which tlie seasoning begins varies with the kind of wood. 



(1) That for oak the seasoning commences in March or April; with 

 pine the exact month can not be decided, as they were not placed under 

 observation until late (April), but all test pieces showed a loss of moist- 

 are within a fortnight after being exposed. 



Ash and white-wood commenced to lose moisture in April, and elm 

 immediately on being exposed in January. 



No law can be deduced from the experiments as to the exact time
