THU JAPANESE BEETLE QUARANTINE 
UNITED STATES CIVIL SERVICE EXAMINATIONS 
The regulations governing llie Japanese Beetle Quar¬ 
antine have been revised. 
A new policy lias been adopted, involving what is 
termed the “Zoning System.” This allows free move¬ 
ment of locally produced products within the quaran¬ 
tined district and gives an opportunity to inspect those 
likely to spread the beetle that are shipped out of the in- 
fected area. 
The regions now listed in New Jersey are as follows: 
City of Bordentown, and the townships of Bordentown, 
Mansfield, Springfield, New Hanover, Pemberton, South¬ 
ampton, Tabernacle and Shamong in Burlington county; 
the townships of Waterford, Winslow and Gloucester in 
Camden county; and the townships of Washington, Man¬ 
tua, East Greenwich and Greenwich in Gloucester 
county. The following townships of Tinicum and Darby 
and boroughs of Collingdale and Yeadon in Delaware 
county; all of Philadelphia county; the townships of 
Cheltenham, Abington and Moreland in Montgomery 
county; the township of Southampton, borough of Lang- 
home, and the townships of Middletown and Falls, in 
Bucks county. 
By having an outer /one or projecting belt drawn 
around the infested area it is hoped close touch can be 
kept with its spread and prompt steps taken to combat 
it. Its natural spread by flight is comparatively limited 
and the object of quarantine restrictions on carrying pro¬ 
ducts is to restrain its spread locally and by long jumps 
by such agencies until means of artificial control can be 
developed or until control is brought about by the intro¬ 
duction and establishment of natural enemies.

By E. C. Hilborn 
This booklet was not written or gotten up to sell 
through book stores, but with the same object the nur¬ 
seryman writes his catalog to create an interest in plant¬ 
ing. 
It is an extremely creditable piece of work and one 
which should be in large demand by nurserymen for the 
use of their salesman and to send to their prospective 
customers. 
To quote President Paul Lindley, “If a nurseryman 
would sit up at nights working for the good of bis busi¬ 
ness and then sell bis thoughts at cost, some of his 
friends should say it with fruits for him.” And that is 
what the author, E. C. Hilborn. has done. 
It is along the line of the books gotten out by the 
market development committee, but exclusively on the 
subject of landscape gardening. It does one thing and 
does it well, presents the fundamental principles of the 
subject. It is not cluttered up with names of plants that 
only confuse the lay reader, but in simple language the 
principles of landscape gardening driving the point home 
with very appropriate illustrations. 
E. G. Hilborn. the author, is proprietor of the North¬ 
west Nursery Company, Valley City, North Dakota and 
naturally treats the subject of landscape gardening along 
the lines to fit northern homes. 
Full information and application blanks may be obtained 
from the United States Civil Service Commission, Washington, 
D. C., or the secretary of the board of U. S. civil service exam 
iners at the post office or customhouse in any city. 
HOW TO GROW ROSES 
By Robert Pyle 
When a man does a good job he ought to be proud of 
it and Robert Pyle has made a good job of bis fourteenth 
edition of “How To Grow Roses.” 
A practical work written by a poet-artist about a sub¬ 
ject of which he is master and that subject Boses is per¬ 
haps the best summary of the work. For the nursery¬ 
man and florist it will act as a winsome introductory of 
the rose to their customers. It ably bridges the gulf that 
separates the commercial rose grower who has roses to 
sell from the would be purchaser, presenting the rose 
family so intimately that the veriest neophyte can hardly 
help but become enthused. 
The book of course is written for the layman and only 
touches lightlv on budding or propagation but the lists ol 
tested varieties, classification, hardiness, descriptions, 
should be invaluable to the nurseryman 
The book contains 189 pages, is handsomely gotten up. 
copiously illustrated with colored plates and hall tones, 
and published by the Conrad & Jones Company, West 
Grove, Penna.
