Special Introductory 
Nematode Resistant 
Peach Seed Offer 
August 12, 19^0 
To encourage greater distribution of 
Nematode Resistant Nursery Seeds, we 
quote 1940 crop as follows: 
Shalil. (U.S.D.A. introduction from 
India — S.P.I. 63850) from our Madera 
property, NOT fruited in ISOLATION. 
$12.50 per thousand seeds. 
Shalil, same as above, also Bokhara — 
fruited in our ISOLATED seed plant at 
Bethany, $17 50 per thousand seeds. 
Yunnan —- S. P. I. 55885 and 55886, 
from Yunnan Province, China, limit 10,000 
seeds each customer, BETHANY ISO¬ 
LATED PRODUCTION, $20.00 per 
thousand seeds. 
This special price offer effects a sav¬ 
ing of about 50% of last year’s prices, and 
is made only for immediate booking. 
Seeds will be shipped during Septem¬ 
ber as soon as harvested and properly 
cured. 
NEMATODE-RESISTANT WILD PEACH Yunnan—S.P.I. 55885, fruiting in 
Kirkman 100 acre isolated seed plant at Bethany, Calif. Seed orchard trees 
were propagated from original LI.S.D.A. importations from Yunnan province, 
China. 
Please mail check in full with orders for less than 
$100.00. Where larger quantities are ordered, send about 
25%—balance draft with bill of lading. 
Cuttings of special Mariana and Myrobalan strains 
selected by University of California for Nematode, and 
hopeful Oak Root Fungus resistance. Write for further 
information. 
We have closely followed U.S.D.A. and University of 
California experimentation in the isolation of Nematode 
Resistant rootstocks — in fact, supplied the land, and the 
Nematodes, and operating costs for the first successful 
California experimentation — in 1928. Each recent year 
Yunnan 55885 impresses us even more favorably than 
other contenders — in more normal growing habits, and ex¬ 
traordinary fruiting when budded to commercial varieties. 
Also its greater relative resistance to infestation, in very 
bad Nematode areas, adds to our favorable impression. 
Of the three Yunnans under wide experimentation, the 
vigorous, small fruit — hard to clean Yunnan Clingstone, 
S.P.I. 55885, is definitely the Nematode resistance winner 
over the entire field (see recent University of California 
bulletin by Mr. Day and Dr. Tufts — "Further Notes on 
Nematode-Resistant Rootstocks for Deciduous Fruit 
Trees.” 
ISOLATION for Pure Strain Seed Production. 
There is no authority so far heard from, who does not 
prefer isolation. Most experienced authorities stipulate 
isolation of three to five miles from non-resistant peach 
or nectarine blooming, as a "MUST” condition, if purity 
of strain is to be maintained—distance depending on 
honey bee population and pollen carrying activity. It is 
costly, and inconvenient to properly isolate, but is very 
much worth while. That is our unequivocal stand. 
Promiscuous natural crossing is responsible for the 
thousand and one variant hybrid seedling varieties that 
come and go in the realm of fruits—as in most else that is 
subject to Nature’s tantalizing foibles. So our Spaniel 
bitch is hurried into seclusion when neighbor Jimmie’s 
Dachshund reconnoiters hither. Likewise no peach nor 
nectarine pollen will rendezvous with our Yunnan and 
Shalil here at ISOLATED Bethany—we are making cer¬ 
tain of that. Thus do we endeavor to keep faith at our job. 
Our stock of fruit trees is up to our Half Century 
standard of dependable nursery stock production-—both 
June buds and yearlings, on Nematode-Resistant and com¬ 
mon rootstocks, in our California and Alabama propagat¬ 
ing plants. 
We hope to serve you.
