Budded trees of many Florida varieties are being tested in Southern Cali- 

 fornia, and the Bureau of Plant Industry expects to send out a large 

 number this spring for trial. One large tree at Sherman which was worked 

 over to the Trapp variety flowered this year for the first time, and numerous 

 other trees are becoming old enough to bear and will be watched with interest 

 for the next few years. This type is certainly more tender than the Mexican, 

 but the past few winters have shown that some varieties at least will stand 

 our average winter temperature without injury. Future experience will likely 

 confirm the present belief that this type will succeed in many locations here. 



Numerous seedlings of Hawaiian, Cuban, and West Indian varieties have 

 been grown, but as yet these have not come into bearing. Budded trees 

 will have to be tested before anything definite can be said of their adaptability. 



It has been stated that the avocado would not succeed in the hot and dry

interior parts of California. Trees are known to have grown without injury 

 as far into the interior as Redlands and Riverside, and have fruited heavily 

 at Pomona and San Fernando, and should be tried at Imperial. 



PROPAGATION 



By Seed. This is the simplest method, and the one most practiced in 

 California up to the present time. The seeds of most varieties are obtainable 

 during late summer and autumn, and should be planted as soon after removal 

 from the fruit as possible. It has been found to hasten germination greatly 

 if the seeds are buried in moist sand or sawdust for a period of two to four
