The number of seedlings obtained from the different plots were 

 as follows : — 



1 Only 5 grams of seed sown. 



In all cases the seeds germinated well, the seedlings coming 

 through the ground equally and showing little variation in 

 growth until about the middle of the first summer, when plot 

 No. I (Scotland) began to lag behind somewhat. Thenceforward 

 this section never looked quite as well as the others. It was 

 more regular than some of the plots and produced a normal 

 quantity of plants, but the seedlings made less progress and 

 had shorter needles. 



The plants from Belgian seed were much the best in every 

 respect, there were no dead needles, no gaps, and the colour was 

 a fine dark green ; although the average height was not more than 

 5;^ inches, many individual plants were 7 inches high. In plot 5 

 (Bavaria) the seedlings were uniformly well developed, the height 

 ranging from 3 to 5^ inches. Plot 6 (Russia, Baltic Provinces) 

 gave small plants but was regular and otherwise satisfactory ; 

 the seedlings had the appearance of being taller than when 

 measured as the needles were held erect over the terminal bud 

 in a curious manner. Plot 7 (Eberswalde) was unequal in 

 growth and decidedly patchy, a fact which is reflected in the 

 comparatively small number of plants produced. The seedlings 

 from the Ural Mountains (No. 8) were strong and equal, and 

 did well considering the small quantity of seed sov/n.
