Nos. 18, 22. Prunus Padus. Nos. 77, 79. Pyrus Aucuparia. 



Prumts Padus. The results in the two trees have so 

 little resemblance that it is safer to take the quick-growing 

 and vigorous-looking No. 22 as truly representative of the 

 average of the species. It shows a slight inferiority in the 

 second half-season, and June is the best month, with 0'46 of 

 annual average amount and 36 p.c. 



Pyrus Aucuparia. Much the same general remarks 

 apply here ; but if we accept No, 79, much the cj^uickest 

 grower and most vigorous-looking of the two Eowans as 

 representative of the species, we get an extreme dispro- 

 portion in the half-yearly p.c, 28-5 and 71 "5. July is 

 decidedly the best month, with 0-37 of annual average 

 amount, and 39*5 p.c. 



Ulmus campestris.
