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 Bahla 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 grea t thing. It Is 
too much to hope for. 
We are going directly back to Bahla 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 Bahla and get our data. Prom what we saw on 
our way down, I believe we will hardly be able to complete 
our studies at Bahla before I shall have to return. There 
is much more material there than we anticipated or were 
given any reason to expect.
