162 LUTHER BURBANK 



that on a good many other lines of experiment, 

 and there is reason to believe that varieties not 

 yet introduced will presently bring a return that 

 will more nearly balance the account; but 

 from my books, lectures, and other sources 

 I have at last, by good business management, 

 now made the account balance well on the 

 right side. 



Meantime, the sums earned for others by the 

 Burbank plums and prunes after they have gone 

 out into the world have been really significant, 

 from whatever standpoint considered. 



As illustrating their earnings in a single field, 

 we may note that in the season of 1912 there 

 were 564 carloads of Burbank plums of different 

 varieties, aggregating 396,133 crates, shipped 

 from California alone to the eastern markets. 

 This represented more than one-third of all the 

 shipments of plums. The average price per 

 crate received for all Burbank plums was $1.20 

 as against $1.03 the reported average for other 

 varieties. The maximum price per crate for any 

 Burbank plum was $3.25 as against a maximum 

 of $3.04 for any other variety; the highest aver- 

 age prices per crate being respectively $1.71. 

 Millions of crates are now (1920) shipped, and 

 prices have ranged from $2 to $4 per crate this 

 season.
