under a jumble of protests over spilt milk. Does Dr. Marlatt 
want that, or does he want “a full and free discussion?”

Questions and Answers 
Please give me some advice when to sow Berbery 
Thunbergii seeds, and the methods generally use for 
good results. G. A. S. 
Barberry seeds should be macerated and separated 
from the pulp as soon as gathered, and sown in the fall, 
when they will come up the following spring. 
The writer obtained good results last year by mixing 
the seed with sand and keeping it in a tlat, placed in a 
cold frame over winter, then sowing in the spring just 
as it began to germinate. 
Sow the seed in well prepared beds in the open. The 
beds should be about three feet wide, convenient for 
weeding and shading.

Gentlemen: In your February issue, under questions 
and answers column, in reply to information requested 
on Rosa multi flora, you state that the flowers are single 
and white. The writer has grown millions of the Rosa 
multiflora, exclusively as a stock for budding upon, and 
cannot remember ever having seen one with a white 
flower, the (lowers being a good full semi-double and 
deep rose pink in color. Very free flowering of course, 
as the name Multiflora implies, our blocks of stock while 
being budded being full of bloom and quite a contrast 
to I he Manetti which very seldom flowered in its young 
stages like the Multiflora. 
Yours very truly, 
F. W. BLOW NURSERIES', 
Per F. W. Brow. 
We should have been a little more explanatory in stat¬ 
ing the color of Rosa multiflora. Like our correspondent 
we described it as we had know it without reference to 
the authorities on classification. 
The Kew authorities state: flowers white, pink or 
purple. 
Bailey’s Cyclopedia of Horticulture, the standard au¬ 
thority in this country, describes it as usually white and 
goes on to state: The typical form which is sometimes 
distinguished as var. Thunbergiana has small single 
white flowers. Var Cathayensis , flowers single pink. Var 
carnea plena, double light pink flowers.

REMEDY FOR PEACH BORERS 
Bulletin No. 796 of the U. S. Department of Agricul¬ 
ture gives an account of the experiments with para-dieh- 
lorobenzene for destroying borers in peach trees. 
The results are summarized as follows:—Para-dicli- 
lorobenzene has proved quite effective over a wide range 
of varying conditions imposed by field practice, with a 
considerable margin of safety for trees six years and 
over. 
In making the application the surface crust about the 
collar of the tree is broken. Excessive amounts of 
gummy exudations at the surface are removed. The 
lower levels of soil are disturbed as little as possible, and 
the required dose is distributed evenly about the trunk 
in a band 1 to 2 inches in width. Two or three shovels 
of earth are then placed over the material, and com¬ 
pacted with the back of the shovel, being mounded slight¬ 
ly to cover surface galleries. 
In the latitude of Washington and northern Virginia 
about September 10 has been found to be the most satis¬ 
factory time of application. Based on the insect’s sea¬ 
sonal history, the theoretical time of application in the 
North generally would be about September 1; in the 
Ozarks, September 26th; and in Georgia and the cotton 
belt, October 10. 
For 6 to 16-year-old trees of average size, doses of one 
ounce and of three-fourths of an ounce per tree have 
been found effective in destroying the borers without in¬ 
jury to the trees. For very large trees of advanced age, 
a somewhat increased dose may be desirable. 
As an added precaution against injury, the base of the 
trees should be uncovered four to six weeks after appli¬ 
cation, allowed to remain open for a few days, and re¬ 
covered. This precaution is especially necessary if the 
application has been made very late. 
The use of para-dichlorobenzene in this way has been 
found to reduce the infestation on the average from 6.77 
to 0.41-0.36 larvae per tree, approximately a 94 per cent, 
control. 
The manufacturing chemists are marketing P-Dicli- 
lorobenzene under the name of Dichloricide, through the 
wholesale druggists in one pound and half pound tins, 
so that any druggist should be able to get it through his 
wholesaler if he hasn’t it in stock.
