or rose colored anthers. The leaves are from broadly 
oval to rhomboidal and from four inches long to 
three inches wide, and usually dark rich green on the 
upper surface and pale beneath. The handsome 
oblong, large, bright scarlet fruit ripens toward the 
middle of September, and when an individual thirty 
feet in height and as much in spread of top is thickly 
covered with ripe fruit, it compels admiration. Cra- 
taegus pedicillata is fairly abundant in the Genesee 
Valley, and was observed by the writer outside the 
northern boundary of Delaware Park in Buffalo last 
fall. 
No doubt C. pedicillata has always in former times 
passed for C. mollis, but the former has hardly any of 
the tomentose, downy or pubescent conditions that al- 
ways are characteristic of the different forms in th(' 
mollis group. 
Crataegus matura, a shrubbery species, first ob- 
served by Mr. J. C. Jack, of the Arnold Arboretum, 
in Massachusetts, in September, 1899, and since then 
has been found in the Champlain Valley, and in the 
•Genesee Valley at Rochester, has been lately described 
and named by Dr. Sargent. It comes into bloom 
about May 21. The habit is somewhat open and 
straggling and grows from six to ten feet in height. 
The chief value of this species is in the early ripen- 
ing, oblongi dark crimson fruit, which ripens about 
the middle of August, and is the earliest of all the 
thorns to ripen fruit here. 
The native thorns are not difficult to transplant, 
provided good care is taken of the roots, and they 
should always be well cut back to insure success, and 
planted in heavy, moist soil. In a wild state they ap- 
pear to abound in limestone soil. 
The seeds take two or three years to germinate. 
For instance, we have had the seeds of C. Crus-Galli 
lie dormant until the third summer in the seed bed. 
But in most cases they will germinate quite freely the 
second season. It is customary to separate the pulp 
from the seeds, and where there is a small quantity of 
seeds that probably pays. We sometimes, stratify 
them in sand for one year, but if we have a good 
many bushels to handle, we sow them at once broad- 
cast on a bed six feet wide, and cover about from one 
and one-half to two inches deep. A heavy mulching 
of manure, or any good mulching material left on 
until early in the second spring, will prevent an abun- 
dant growth of weeds, and a little hand weeding will 
be all that is necessary. 
In order to secure flowering plants of the new spe- 
cies as quickly as possible, in the winter time, Mr. 
Jackson Dawson, of the Arnold Arboretum, crown 
grafts the scions on to young seedlings of Crataegus 
Crus-Galli preferably, or whatever suitable seedlings 
of Crataegus he has available, and grows them along 
in small pots in the propagating house. They are in 
good condition for the nursery rows in spring, and 
he has remarkable success, as we noticed last summer.

Elm Tree Beetle. 
The New England Association of Park Superin- 
tendents has issued Special Bulletin No. 15 on the 
Elm Tree Beetle, containing many valuable sugges- 
tions for the extermination of this pest, from which 
we digest the following information. 
The beetles hibernate in old buildings, garrets, chim- 
neys, old trees, etc., come out of winter quarters in 
May, and begin to hatch out larvae in July. 
Spraying should be commenced in early spring, and 
the two mixtures strongly recommended are Kerosene 
Emulsion, and the arsenate of lead preparation known 
as Disparene. The most successful formula for the 
arsenate of lead is that given by the Hatch Experi- 
ment .Station of the Massachusetts State Agricultural 
College. Dr. L. O. Howard’s pamphlet on the use of 
steam spraying apparatus, reprinted from the year- 
book. Department of Agriculture, for 1896, and New 
York State Museum Bulletin, Vol. 5. No. 20, entitled 
^‘The Elm Leaf Beetle in New York State,” by the 
State Entomologist, Mr. E. P. Felt, are also recom- 
mended. 
The consensus of opinion as to the method of pro- 
cedure is to spray the trunk and lower limbs with 
Kerosene Emulsion, and, the upper foliage with arsen- 
ate of lead, being careful to apply it to both sides 
of the leaves. The loose bark should be scraped from 
the trunks and burned, as it is generally thickly popu- 
lated with the pupae and larvae of the obnoxious in- 
sect; some sprayers recommend scrubbing the trunk 
with a strong brush instead of spraying it, and some 
advise spraying the ground under the tree as well. 
Mr. Jackson Dawson, of the Arnold Arboretum, says: 
‘Tf vigorous measures are not used during the coming 
season many of our trees will present a sorry appear- 
ance the coming summer.” He urges spraying the 
trunks with strong Kerosene Emulsion, and the tops 
with Paris green or London purple with flower of lime 
added to keep the foliage from burning. 
The Bureau of Parks, of Albany, N. Y., gives the 
total cost of operating a spraying plant from May 13 
to September 13, as $2,077.20, comprising $1,704.55 
for labor, and $372.65 for materials, repairs, etc. The 
plant in use consisted of two gasoline motors and 
two three-piston “Gould” pumps, with 100 gallon tank 
to each motor. The number of trees sprayed aver- 
aged 80 a day, making the average cost per tree 22 
cents.
