HISTORY OF A BRANCH 3 



off to 0), it is seen that it grew to 1894 the first 

 year. The second year it grew to 1895; and in 

 that year, also, one branch, r, was developed. 

 It is noticeable, too, that two branches started 

 from the end of the 1894 growth, but one of 

 them failed, and only a short stub now records 

 the fact. The third year the branch grew to 

 1896, and a very small branch, q, now dead, was 

 produced on the growth of 1895. The fourth 

 year (1897) the branch grew to o, and a single 

 shoot, p, grew on the growth of 1896. Altogether, 

 this branch has made forty efforts to produce 

 branches (that is, forty buds on the growths pre- 

 vious to 1897, but not all traceable in the illus- 

 tration), only five of which, r, at 1894, q, p, and 

 o have been successful; and of these five branches, 

 two are dead, and only one, o, seems likely to 

 persist. That is, in the struggle for existence, 

 only one effort in forty has been successful. 



The large branch on the left, terminating at i, 

 may now be examined. The first year it grew to 

 1894. The second year it grew in the direction 

 Z, but that branch died and the year's growth was 

 lost. The stub or remains of this branch is seen 

 at /. The third year the branch grew to 1896. 

 The fourth year (1897) the terminal branch grew 

 to ?', a side branch to j, and another side branch, 

 now nearly dead, grew to k. The entire branch 

 (1893 to i) has made over twenty efforts at 

 branches, four of which efforts were successful,
