to butternut and black walnut. Shagbark hickory will be planted in 

 1941. This is the first attempt, under this project, at direct seeding, 

 although this was a part of the plan as originally set up in 1912.

A Study of White Pine Stands (C. L. Stevens and L. C. Swain) 



Stands of white pine in the northern part of the state have been 

 examined in an attempt to locate a strain of trees having side branches 

 of small diameter. This work is to continue, and seed from selected 

 stands will be collected during the next good seed year. These seeds 

 will be tried out in the nursery and plantations to see if this type of 

 crown can be propagated. 



The sample plots of white pine lost in the hurricane of 1938 have 

 not been replaced, but it is expected that a complete series will be ob- 

 tained in the near future.

Spruce Reproduction Studies (C. L. Stevens) 



In 1935 plots of spruce were established in a partial cutting and 

 a clear cut area, and subjected to four methods of treatment as fol- 

 lows : 



Plot 1. All brush and litter were removed, leaving the mineral 

 soils completely exposed. 



Plot 2. All brush was removed and the litter raked oft" small 

 spots, two feet square. 



Plot 3. All brush was removed and the soil scarified. 

 Plot 4. The brush was removed, the soil scarified, and the brush 

 replaced. 



In 1940 the area was visited and a tally made of all growing 

 species on the experimental and check plots. The results of the tally 

 give no indications that any of the treatments produced a satisfactory 

 increase in the amount of spruce reproduction. There is a possibility 

 that the seed supply has not been adequate during these five years, 

 and for this reason it seems advisable to continue the work for a 

 longer period before drawing any conclusions.

Fence Post Durability (C. L. Stevens) 



The original data on this project, which was begun in 1929, were 

 lost in a fire in 1937, and some of the posts have been moved to new 

 locations. In 1940 only 60 of the original posts were located, 49 of 

 which appeared to have been treated and 11 apparently untreated. 

 It was impossible tc determine the type of treatment of these posts, 

 but all which had been treated appeared to be sound and in good 

 condition. Eight of the untreated posts had rotted off and were lying 

 on the ground ; three were still in use but the posts underground had 

 rotted very badly.
