During the last 10 or 12 years we have doubtless im- 
ported the greatest assortment of new and rare woody 
plants brought into the country during that period. 
Also we have been working pretty hard at plant breed- 
ing during the same period with rather encouraging results. 
As rapidly as possible we are dropping all common lines 
and concentrating © on novelties and specialties. These are 
the things that are in demand nowadays. 
Hence this list is well worth very careful study if you 
take interest in trees and shrubs which are out of the 
ordinary. 
Several novelties either imported or originated by our- 
selves are now being introduced on an exclusive basis by 
certain first-class retail catalog houses who wish “leaders” 
of high quality. We have more of these items coming along 
and shall be glad to explain the arrangement on request. 
EXPLANATION OF 
HARDINESS RATINGS 
As this list goes all over the U.S.A. (and abroad in peace- 
ful times), we believe it a good idea to indicate hardiness. 
This has been done by giving after the name of each item 
a number in ( ) indicating the zone up to which it is con- 
sidered hardy.  - 
Our authority through Zone 7 is Rehder’s atbook For 
Zones 8 to 10 we have been guided by Pacific Coast experi- 
ence and have sub-divided Zone 9 so that 
(9) indicates probably safe to 20° (Sacramento and San 
Joaquin Valleys, etc.). . 
(914) indicates probably safe to 25° or 26° (San Fran- 
‘cisco Bay Region; etc.). 
(10) indicates will stand only very light frost. 
To find the zone you are in refer to map on center pages 
-of this book, which we use by the courtesy of Arnold Ar- 
boretum and McGraw-Hill Book Co. 
Please understand that all ratings show our honest opin- 
ion, but we disclaim all responsibility for their correctness. 
We hope this innovation will be helpful to nurserymen 
- all over the country.

LINING OUT STOCK— 
For convenience, this is assembled on pages 31 and 32. 
The list comprises mainly new and uncommon items, so 
deserves careful scrutiny. 
POT GROWN AND GALLON CAN sTOCK— 
We find that many customers, especially those at a dis- 
tance, prefer to have us remove soil and ship “bare roots” 
packed in moss. Wherever possible, this should be done 
this season on account of great scarcity of labor, shortage 
of packing boxes, etc. So if you order this class of material 
please be sure to say whether you want it packed with or 
without soil on the roots. 
California nurserymen will please note that 4-in. pot 
stock in body of list can be transferred at once to gallon 
cans for immediate sale, while the smaller sizes for grow- 
ing on, together with Qu, and 3-in. pot stock, will be found 
‘at end of list.
