in market is very heavy naturally. I have tried to point 

 out these matters more fully in our notes to you under 

 separate cover. 



Through our consul, Mr. Lay, I got in touch with the 

 leading nursery firms of Brazil. We can secure such fur- 

 ther material, budwood, trees or plants or seeds from them 

 by correspondence. In their citrus nursery we found a 

 citrus tree having marvelous leaf variability. We se- 

 cured budwood, etc., and I know that it will be of great 

 value in further breeding work. The leaf mutations are 

 as marked as our fruit mutations in California. 



We have found about all the California citrus types 

 here and many others besides. I really feel that we have 

 been well repaid for our trip already. It has been of In- 

 estimable value to me. For one thing I have been forced 

 to work out a satisfactory fruit and tree scoring system 

 that will give definite and concrete data. It works like 

 a charm. 



We have found the female nematode Tylenchus semipene- 

 trans but have not gotten the male yet. We have had but 

 little daylight to devote to it so far. We found the 

 galls and living nematodes in the galls of tomato plants. 

 At Bahia we will have time to go into this matter care- 

 fully. If we could discover any signs of stock resistance 

 to the nematod here, it would be a great thing. It is 

 too much to hope for. 



We are going directly back to Bahia because the trees 

 and fruits of the navel orange should be studied now. 

 Otherwise we should have to wait until next summer to get 

 adequate ripe fruits for study. So we decided to return 

 directly to Bahia and get our data. From what we saw on 

 our way down, I believe we will hardly be able to complete 

 our studies at Bahia before I shall have to return. There 

 is much more material there than we anticipated or were 

 given any reason to expect.
