5. UNUSUAL GROWTHS OF TWIGS OF SEVERAL PLANTS 

 IN THE SEASON OF 1916. 



Along with the unusual flowering of certain plants we have 

 noticed indication of abnormal twig development during the 

 season just passed. We noticed this in the apple, apricot, 

 peach and pear. The unusual appearance is in the fact that 

 the twig which has all developed this season has the appear- 

 ance of two or more intermediate zones of bud-scale mark- 

 ings. Thus the appearance of two or three years' growth 

 results in the same season. Naturally, then, we cannot always 

 depend upon external appearances in determining the age of 

 a twig. It may be that more careful examination would solve 

 the question, but a cursory one will not. 



The presumption is that one or two regular, or seemingly 

 regular, winter or resting buds were formed by the twig, and 

 then growth was again resumed in the same growing season. 

 This all occurred in these trees without any artificial influence 

 so far as we know. There was no watering done except what 

 nature did. Indeed, we lost several trees this year from 

 drowning, we are inclined to believe, and hence we were not 

 tempted to add any more water. 



The proof that the part of the twig in question grew all 

 this past season is in the fact that this same part had the cloth- 

 ing of leaves on it that only results from the elongation of a 

 terminal bud. Then in this particular case we had pruned 

 the trees this spring and the place of pruning is still plainly 

 visible, or enough so to determine what part of the tree grew 

 this year.
