for fuel or for sale without the necessity of the cone-purchasers, 

 etc., entering the true drying-rooms. 



VI. Bmpty-cone Shed. 



This can be built, as cheap as possible, with board walls and a 

 floor made secure against the entrance of dampness. On 

 account of the fire danger it is recommended that it be built with 

 walls closed on all sides, and made air-tight possibly with roofing- 

 paper or better, calked with oakum, and of such size that the 

 whole drying process will not be interrupted and harmed by an 

 inopportune overflow of cones. 



VII. The Wing Removing Room. 



The winged seed gathered in the churn-room is here, once a 

 day, put into sacks. 



If cones from different collectors or for different tests are kiln- 

 dried on the same day, each kind is sacked separately. The 

 winged seeds are in these sacks freed from the wings by carefully 

 beating the sacks with soft leather flails and grinding them 

 around frequently. 



This method is the most careful one known to me. If well 

 carried out, it removes the wings from Scotch pine seed with such 

 completeness that, in the plantations, the seed runs smoothly out 

 of the smallest aperture of the seeding machine. With seed from 

 which the wings have been so removed, it has been possible to 

 distribute evenly, with the Drewitz machine, 4.4 pounds (2 kg) in 

 6.2 miles (10 km) of seed furrows. 



Other methods leave behind wing particles or injure the shells 

 of the seed. 



Each sack is given an enclosed label with the notations : Kiln- 

 dried on ; Cones delivered by ; Derived 



(Date.) (Name.) 



from kiln-dried cones, winged seed. Thus 



(bushels.) (pounds.) 



one can easily prove, by germination tests of each sack, the 

 quality of the supply and care exercised on each particular drying 

 day. 



The sacks are then finally hung up in this room for several
