NEW ITEMS 
During the last 10 or 12 years we have doubtless 
imported 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 
breeding during the same period with rather encourag- 
ing results. 
We are continually dropping common lines and con- 
centrating 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 arrange- 
ment on request. 
EXPLANATION OF 
HARDINESS RATINGS 
As this list goes all over the U. S. A. and also abroad, 
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 
considered hardy. 
Our authority through Zone 7 is Rehder’s Handbook. 
For Zones 8 to 10 we have been guided by Pacific Coast 
experience and have sub-divided Zone 9 so that 
(9) indicates probably safe to 20° (Sacramento and 
San Joaquin Valleys, etc.). 
(9%) 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 Arboretum and McGraw-Hill Book Co. 
We hope this innovation will be helpful to nursery- 
men all over the country. Please understand that rat- 
ings show our honest opinion, but we disclaim all re- 
sponsibility for their correctness.

LINING OUT STOCK— 
For convenience, this is assembled on page 27. 
The list comprises mainly new and uncommon items, so 
deserves careful scrutiny. 
POT GROWN AND GALLON CAN STOCK— 
We find that many customers, especialiy those at a 
distance, prefer to have us remove soil and ship “bare 
roots” packed in moss. If you order this class of ma- 
terial 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 gal- 
lon cans for immediate sale, while the smaller sizes 
for growing on, together with 2% and 3-in. pot stock, | 
will usually be found at end of list.
