with an averag'e of 7,000 trees per 100 

 square feet of nursery bed surface. Tbe 

 trees were separated into the three fol- 

 lowing grades : 



Grade I. — T arg,c and thrifty. 



Grade II. — Medinm. 



Grade III. — Small and weak Tdis- 

 cards). 



After being graded tlie trees were tied 

 np in bundles of fifty each. A com- 

 parative study was then made of the 

 three grades on the basis of size, weight 

 and volume, and the resuhs follow:

Wdietlier or not to grade forest tree 

 seedlings does not seem to be a question 

 anv longer. The time seems to be at 

 hand and good management recom- 



mends that all nursery stock should 

 be carefully sorted and classified. 



The big question, however, seems to 

 be what to do with grade TIT. seedlings. 

 Some nurserymen entertain hopes for 

 these underlings, while others protest 

 against their resetting in the nursery. 

 The former claim that the trees are in- 

 herently strong but have been unfavor- 

 ably situated, while the latter insist that 

 they possess inherent weaknesses and 

 defects. In order to throw some light 

 on this unsettled subject over 1000.000 

 small trees of different species, ffenerallv 

 classified as culls, were transplanted in 

 the nurseries. Their development is be- 

 ing watched in both the transplant beds 

 in the nurseries and in plantations. The 

 results are not yet conclusive, but indi- 

 cate strongly that trees, such as the 

 three small ones at the right of the ac- 

 companying illustration, are not fit to 

 iraiisplant. They are weaklings, an'l in 

 many instances have been suppressed 

 lievond recovery.

WHY NURSRY STOCK SHOULD UK GRADED. 

 All the trees are threc-year-oUl Norway Spruce taken from tlic same bed... The three small trees on the 

 right are culls. Thev shoiiKl he iliscanlcd, for they have been siipprcsseJ beyond recovery.
