Another adaptation of structure exhibited in 

 this tree is the great gnarled expansion of its 

 trunk at the base, which may be seen in the 

 plate and vignette, thus supporting it against the 

 wind by what may be called a circle of buttresses." 

 Mr. Murray, in "Notes on Californian Trees," 

 in "Edinburgh New Philosophical Journal, April, 

 1.860." 



Here is another extract from the same Journal : 

 "Comparing the growth of the swallow fed 

 by the parent birds, with that of the young 

 of the turkey, common fowl, and goose, which 

 have to find their food, a marked difference is 

 observable, the growth of the one being so much 

 more rapid than that of the other. Again, if 

 we compare the eggs of these birds, which feed 

 their young till they are capable of taking wing, 

 with the eggs of those which have to provide for 

 themselves, the latter will be found proportionally 



larger How little, as regards size, does the 



egg of the eagle 4iflcr from that of the goose; 

 how very small is the egg of the cuckoo compared 

 with that of the partridge, the latter birds dif- 

 fering but little in size. And is there not design 

 in this, as well as in the different degrees of 

 rapidity of growth? Is not the gosling during 

 the first days of its existence, after leaving the 

 egg, more dependent for nourishment on the re- 

 sidual included \olk than the eaglet? and is it 

 not so in other instances. 



In the mammalia there appears to be a relation 

 between the period of growth required for the
