[Sess. 



The average of the two Ehiis gives a nearly equal p.c. for 

 the half-seasons, and the increase was much alike through 

 the first half-season ; but as No. 93 decidedly outgrew No. 

 94 in the second, the half-season results are somewhat in 

 favour of the second period in the former, and of the first in 

 the latter. June is the best month, with an annual average 

 amount of 050 in both, and a proportion of 30 p.c. in No. 

 93 and of 36 "5 p.c. in No. 94. July in No. 94 comes close 

 up, with 0'45 of amount and 26*5 p.c. The growth is well 

 distributed over the season, the amount in April and 

 September being quite appreciable. 



Fraxinus excelsior. 



The discrepancies hero are so great that it is better to 

 accept No. 23, much the quicker and steadier grower of the 

 two, as representative of the species. No. 75 grew pi'ctty 

 much on a par with it in the first half-season, but failed 

 almost entirely in the second. The half-season proportions 

 of No. 23 (57 and 43 p.c.) agree pretty well with those 

 for the old Craigiehall Ash No. G* (02 -5 and 37"5 p.c). June 

 was the best month in both tlic young trees, the amounts 

 averaging nearly alike, 0'31 and 0"28, but the pro])ortions, 

 from the failure of No. 75 in the second half-season, being 

 very different, 34 and 53 p.c.
