New England Trees in Winter, Blakeslee and Jarvis, 
vStorrs Agricultural Experiment Station, Bulletin No. 69. 
This is not a bulletin in the ordinary usage of the teinn, it 
is a volume of nearly 250 pages, splendidly illustrated. It 
contains a dcscri])tion of the principal trees of New England, 
as seen in wintertime. Each tree is discussed under the 
following heads: habit, bark, twigs, leaf scars, buds, com¬ 
parisons, distribution in New England and in Connecticut, 
quality and characteristics of wood. The descriptions are 
supplemented by half tone engravings, giving a view of a 
mature tree, of the characteristics of the bark, the fruit and 
its accessories, and the annual shoot, showing bud character¬ 
istics. 
The work is introduced by an explanation of the method of 
handling the subject, the means of securing the height of a 
tree by a simple system of measurement, and a discussion of 
the winter characters of trees used in distinguishing them. 
Following this is an analytical key, carrying the form either 
to the genus or the species, in many cases to the latter. 
As a means of stimulating interest in our handsome and 
adapted native trees, and a means of identifying the com¬ 
moner forms, this bulletin will be invaluable. It should be 
in the hands of every nurseryman, and will, when combined 
with such works as those of Romeyn Hough and C. S. Sar- 
% 
gent, provide the nurseryman with a working library of 
great value. , 
PROPAGATING THE WALNUT BY BUDDING 
An interesting method of budding the walnut is described 
by E. J. Kraus in circular No. 16 of the Oregon Agricultural 
College. By the method described, it is claimed that a stand 
of from seventy to ninety per cent should be secured. 
In this method the Persian, the American black, and a 
hybrid between the California black and the Persian walnut 
were used. The method differs from the ordinary bud 
method in that it uses one year old buds, which are found at 
the base of the current year’s growth. These are the buds 
which have remained dormant while the terminal bud con¬ 
tinued the growth of the branch. There are usually on the 
branch at this point several buds, some much plumper than 
others. Only the plumpest ones should be used. The author 
has also used buds from wood cut during the winter and 
carried through in a dormant condition. The scions are 
placed in moist sand for a couple of weeks before budding is 
done, which has the effect of loosening the bark so that they 
may be readily removed. 
The method is practically the patch bud method, which 
consists in removing the dormant bud with an oblong piece 
of bark attached and planting it. on the stock in an incision 
made to fit. The bark only is removed with the bud, no 
wood being allowed to adhere. The bud is set beneath the 
bark of the stock somewhat after the fashion of the shield bud, 
it being partly covered by the overlapping flaps of the bark 
of the stock. The bud is wrapped snugly with raffla, and the 
jioint of union then covered with grafting wax. The budding 
is done in June on the Pacific Coast. The stocks are headed 
back about fifteen days after the budding, at the time when 
the bandage is cut. In cutting the stock, it is not removed 
entirely, but is cut on one side, broken down, and allowed to 
remain attached, in which position it aids in carrying off 
surplus sap, and prevents excessive sprouting from the roots. 
When the scion bud starts into active growth, the top should 
be removed entirely. After this is done, the growth of the 
bud is usually rapid, so rapid, in fact, that it will need staking 
in order to prevent breaking down under stress of wind and 
storm. A growth of four to six feet may be expected the first 
season. 
FROST FIGHTING STUDIES IN THE ROGUE RIVER 
VALLEY 
An interesting bulletin from the Oregon Agricultural 
College, by Prof. C. I. Lewis and F. R. Brown, covers the 
experience of two years in fighting frost in the Rogue River 
Valley. Among the conclusions reached by these workers are 
the following; Oils with a paraffin base are to be preferred 
to those having an asphalt base. Oil heaters alone were used. 
These were of the Bolton and Troutman types. These 
investigators recommend the use of cement storage tanks 
where large quantities of oil are to be stored, and galvanized 
tanks for small quantities. At thirty degrees atmospheric 
temperature, twenty heaters per acre had no influence in 
raising the temperature. Twice that number raised it one 
degree. It does not appear that less than one hundred 
heaters per acre is likely to be efficient in periods of distinctly 
cold weather. 
The cost of heating ah acre for a four hour period was $5.10 
for oil. This took no account of the cost of the equipment, 
but included labor and oil. The investigators conclude that 
there is no doubt that a crop can be saved by orchard heating. 
The experiments are to be continued. 
“Severe frost and some two and one-half feet of .snow have stopped 
Boskoop nurserymen from shipping stock to this country, which they 
had just started doing. Where most of the American firms have the 
bulk of their imports in Spring, it shoWs the advisabilit}'’ of having at 
least part come in Fall, especially those who have cellars should do so'in 
order to have goods when they are wanted.”
