 the forest near Keene as opportunity permits. The school now owns 

 approximately 2.500 acres of forest, with funds available to increase 

 this by several hundred acres. 



Gkr.mi.vatiox of Yellow-poplar Seed 



To those foresters who have occasion to handle yellow poplar 

 (Linodcndron tiilipifcni) in the nursery, the results of an experiment 

 at the University of Michigan may be of interest. 



Having had very poor success in securing germination of yellow- 

 poplar seed when bought from dealers and stored in sacks in cold stor- 

 age, it was necessary to locate the trouble. 



Through the courtesy of ^Ir. I. C. Williams, Deputy Commissioner 

 of Forestry of the State of Pennsylvania, a supply of the seed was 

 obtained in the fall of 19 17 which was fresh from the trees. 



Upon receipt of this seed, in November, two pounds were sown im- 

 mediately in a 4 by 12 bed and covered with a mulch of leaves. A 

 second lot of two pounds was stratified in moist sand, and the box con- 

 taining the sand and seed was buried in sandy, well-drained soil. A 

 third lot, also of two pounds, was placed in a cloth sack and hung in a 

 cool, dry cellar. In May, 1918, the second and third lots of seed were 

 sown in 4 by 12 beds in the usual way. 



A count of the seedlings in each bed, made in October, showed the 

 following results : 



Lot No. I (seed sown in fall) 487 seedlings 



Lot No. 2 (seed stratified and sown in spring) 1,088 seedlings 



Lot No. 3 ( seed kept dry and cool, sown in spring) 8 seedlings 



The conclusions are obvious. Seed should be obtained fresh from 

 the tree and kept moist and cool until sown. Under our conditions, 

 spring sowing with this species is apparently better.

The cost of operating the National Forests for the fiscal year ending 

 June 30. 1918, was $4,000,000, plus $700,000 special deficiency appro- 

 priation because of the very serious fire situation. The receipts for 

 this period totaled over $3,574,000, exceeding those of the previous 

 year by almost $120,000. All revenue-producing activities of the for- 

 ests, excepting the timber business (lessened in consequence of the gen-
