EUCALYPTUS TREES. 19 



from actual measurement, of four and one half inches 

 in circumference yearly. At Hamma and at Cannes, 

 near Algiers, the growth in height of young trees 

 averages nineteen inches per month. A stalk one 

 year old, planted in May, attained the height of 

 nineteen feet the following December ; the year after 

 it grew nineteen feet ; the year after it grew nine- 

 teen ieet ; the latter part of the third year this 

 impulse diminished, but, at the end of fifteen years', 

 the tree was over seventy feet in height. 



At "Ellwood," my home, twelvemiles west of Santa 

 Barbara, I have growing about fifty thousand trees. 

 The oldest were transplanted in February, three years 

 ago. These trees, however, have not done so well as 

 those planted one year later, for the reason that the 

 roots were too much confined — the transplanting 

 delayed too long. The best growth obtained, under 

 the most favorable circumstances, is a tree growing 

 near my house, three years and one or two months 

 from the seed. Transplanted two years and ten 

 months, is nine and one half inches in diameter and 

 forty-two feet six inches high. There is another tree 

 near by, same age, transplanted at the same time, 

 not so large in the trunk, but has attained the height 

 of forty-five feet six inches, equal to forty-seven hun- 

 dredths of an inch per day, fourteen and seven nine- 

 teenths inches per month, and, in order to attain a 

 height of four hundred feet, would have to continue 

 on growing at this rate for twenty-eight years. Nine 

 and one half inches in diameter for three years and 

 two months is equal to three inches yearly, or nine 

 and forty-three hundredths in circumference yearly. 

 To make a tree sixteen fe§t jn diameter would have
