1887-88,] Annual Increase in Girth of Trees.

was unusually fine in 1887, a dry warm season, and the tree 

 produced a great quantity of half-sized, pretty well-filled 

 nuts. 



GENERAL HISTORY OF THE SPECIES. 



B. Evergreen Trees. 

 Sequoia gigantea. 



Of these Sequoias Nos. 25 and 27 stand clear of other trees 

 on the terrace, and the others are in the small grove of 

 Sequoias in the Botanic Garden. All were noted in 1878 as 

 being " crowded with branches to the ground." No. 25 is 

 now, however, very inferior in appearance to the others, 

 having many withered branches and its stem bare below. 

 No. 27 is still clothed to the ground, but has lost its crowded, 

 branched aspect, and like all the Sequoias in the garden 

 which have passed their early youth, its stem has acquired 

 an unnatural thickness below and a thin sinuous character 

 at the top. The two in the grove are equal in height, but 

 the branches in No. 1 are fewer than and not so long as in 

 No. 2, and the same changes are beginning to appear in it as 

 in No. 25. 



The average annual increase of the four, 1*22, is probably 

 abnormally low, as No. 25 has evidently not been thriving ; 

 withdrawing it, the average becomes 1'35. No. 25 was 

 measured in 1878 at 1 foot from the ground. Its increase 

 there in ten years is 13 inches, or 4 inches more than at 5 

 feet from the ground. 



The inferiority of No. 25 to the others in the upward as 

 well as the outward growth of the stem is shown in the 

 following statement : —
