begin to fruit in a very short time. Likewise, I have another case in which a 

 Cambodiana scion has been inarched on to a number eleven mango, and on another 

 limb of the same tree a Pakiri has been inarched. The Cambodiana and Pakiri 

 are of about equal growth. They compose now the entire top of a large mango 

 tree. The Cambodiana has been a regular and constant fruiter, while the Pakiri 

 has shown no tendency to bloom, although some Pakiri trees on what is probably 

 Eleanor stock are blooming and fruiting abundantly. From the isolated instances, 

 it would appear the number eleven proves to be an excellent stock for Cambodiana, 

 but proves to be a poor stock for Pakiri and Totafari groups." 



These results seem to indicate beyond the possibility of a doubt that the 

 question of stock is of the utmost importance. It will be both profitable and neces- 

 sary, therefore, when a choice variety is found adapted to Southern California, 

 to experiment extensively and determine what stock is best suited to it. But the 

 subject will require thorough investigation and experimentation before it is clearly 

 understood. 



Varieties 



While the following varieties do not by any means include all the mangos 

 so far fruited in California, they may be considered as all which are worthy of 

 notice or liable to be propagated, and hence the only varieties now grown here that 

 it will be necessary to distinguish by name. With one exception, they have origin- 

 ated locally as seedlings. The exception is the variety Red Number Eleven, 

 which, as described, is produced by an inarched tree sent out by the Department 

 of Agriculture. The presence of this one inarched tree is of the greatest interest, 

 and it has demonstrated a number of things which could not be determined by 

 seedlings. Being of a variety whose habits are well known, its behavior can be 

 taken as an accurate indicator of what the mango will do in Southern California, 

 under such conditions as this tree has been grown. It has produced abundantly 

 and regularly, and the fruit has been fully as large as that produced by the same 

 variety in Florida or the West Indies. In addition the fruits are uniformly well 

 developed, which is not the case with the fruits produced by any of the local 

 seedlings. While the growth of the tree has been much slower than it would have 

 been in a hotter country, it is in a healthy and vigorous condition, and is rarely 

 affected by frost, although it has not been subjected to our average winter tem- 

 peratures, perhaps, on account of being grown in a very mild locality. The locality 

 in which it was grown being near the seacoast, it also lacks the intense summer 

 heat found further inland, and this fact is accountable for the failure of the fruit 

 to ripen perfectly, or even to as great a degree as at Sierra Madre. The cool 

 nights and mild days have the effect of greatly retarding the development of the 

 fruit, so that it reaches maturity just as the winter season is coming on and is 

 unable to ripen for lack of heat. When picked and laid away for awhile, the 

 fruits become soft and eatable but cannot be said to be up to the standard in this 

 respect, by any means. 



Most of the seedlings differ from this inarched tree in setting an enormous 

 crop of fruit each year and then bringing only a few to maturity, probably the
