LAKE GITY, FLA. An increasing shortage of labor has resulted in
steadily declining production of tu'penvina and rosin, basic materials which
enter directly into the production of shrapnel, waterproofing for tents, insu-
lation for ships, smoke screens, amokealss powder, and a long list of items
essential to the war economy and civilian needs. As a result of several years
of intensive'research by the Lake Gity Branch of the Southern Forest Experi-
ment Station, a method has been developed to stimulate the flow of resin by the
application of chemicals to the freshly out streaks which, if and when gener-
ally adopted by naval stores operators, should contribute materially toward the
solution of some of their production problems, according to H. L.* itohell,
Senior Silvioulturist in Charge. The method calls for the application of a
solution of sulphuric acid to the fresh yield streaks. It has been found that
a 40 per cent solution of sulphuric acid is most effective on slash pine,
whereas a 60 per cent solution works best on long leaf pine. Mr. Mitohell
says "Sulphuric acid is particularly effective in stimulating the yields
from virgin timber. In several tests made at the Olustee Experimental Forest,
eight acid treated streaks on virgin faces produced from 53 to 103 per cent
more gun than the same number of untreated streaks on otherwise comparable tim-
ber* Equally good results have been reported by a number of producers who have
tried this treatment on a commercial scale. Although the early production
step-up is especially effective on virgin timber, it will also increase the
early-season yields from yearling and older faces, which should appeal to
operators who are not in position to use chemicals throughout the season but
who are anxious to get their timber into production early in the year."
Another procedure that has given very satisfactory results consists simply of
applying aulphurio acid, immediately after chipping, to a.L streaks chipped
during the spring and summer months* Results of studies carried on at the
Iustee Experimental Forest show that weekly streaks treated with acid produced
from 40 to 60 per cent more gum than untreated streaks added at the same fre-
quenoy. The yields from streaks chipped and treated on the average of once
every two weeks range from 50 to 120 per cent higher than from the same number
of untreated streaks added at comparable intervals, while streaks chipped and
treated on the average of once every three weeks gave a yield of 75 to 130 per
cent more gun than the same number of untreated streaks. This treatment has
given consistently good results in a series of careful experiments conducted
during the past two years, and has been used successfully in commercial opera-
tions. A third procedure that has given good results experimentally during the
past two years, but has not yet been tested on large-scale operations, is the
"skip" acid treatment in which the timber is chipped weekly and the fresh
streaks treated with sulphuric acid every other week* Experimentally timber
thus treated has consistently yielded 40 to 45 per cent more gum than untreated
timber chipped weekly according to current practice. The greatest obstacle in
the way of the adoption of chemical treatment by operators generally this sea-
son is the lack of satisfactory spray gun for applying the solution, but one
has been designed and it is hoped it will be available in quantity by the time
the 1945 operating season opens.

WVAYOROBS, GA. On the light-t4etured, sandy soils in this section
the root knot nemtode is one of the most serious pests of peach treaso In
fact, the sandy soils throughout the Ooastal plain section of the State are so
generally infected with enmatodes it has been almost impossible to grcw peaches
successfully, even in the home fruit orchard. A local Ware County farmer be-
lieves he has found the answer to this problem, and has the proof to support
his belief. Four years ago he set a number of peach trees of several varieties
including alberta and Hiley that were budded on Shalil peach understock, a
native of India that was introduced into this country several years ago by the
USDA. These trees were set on light sandy soil, have made a vigorous growth,
are still in a healthy condition, and are carrying a good crop of fruit. At
the same tine he set on an iL.ediately adjacent plot a like number of trees of
the siane varieties which were budded on the coimon rootstocks. None of these
trees are left, and this grower reports thyt all of them were killed by root
knot within two years after setting. Based on the experience of this grower,
it would now seen feasible to grow peaches on the sandy soils in this section,
particularly in the hoei orohard. .~orkers at the Georgia Coastal plain E.x-
perimaet Station at Tifton report that they have found peaches budded on Shalil
rootstock highly resistant, although not entirely immune to root knot attack,
and they are recommending this rootstock for peaches in the Coastal plain sec-
tion of the State.

AUBURN, ALA. Interest in growing edible soybeans indicates that
the nutritionists have done a good job in convincing gardeners that soybeans
should be included in every rural and urban garden, says Dr. H. R. Albrecht,
Plant Breeder with the Alabama Experinent Station. In discussing reasons why
more soybeans should be grown he says they are easy to gro. and show a consid-
erable resistance to drought and insect attack. They are not susceptible to
weevil damage, and present no serious storage problems. They are high in nu-
tritional value, their protein and fat content is nuch greater than that of
oowpeas and lima beans, and they are appreciably richer in calcium, phosphorus,
potassium, and magnosiumr They are also good sources of some of the vitamins
Varieties of edible soybeans reoorrended for use in Alabaca are Rokusun, Tokyo,
Seminole, and Cherokee. The Rokusun is an early variety, is prolific, produces
green beans of large size and excellent quality, and dried beans with many de-
sirable characteristics. The Tokyo is also an early bean of good quality and
flavor, especially in the dry bean stage. The Seminole and Cherokee are very
late in maturity, and do not bear green beans for table use until some time in
September. They are very prolific, at least as far as green beans are con-
cerned, but their production of dry beans sometimes is affected adversely by
insect attack or frost. Of the late maturing varieties tested here the Semi-
nole is preferable. It is somewhat earlier than the Cherokee, has proven to
be a good yielder, and is superior to uost other varieties froa the standpoint
of green and nature beans. It is particularly desirable as a dry bean because
it is large-seeded, and the seeds swell and soften uniformly upon soaking.
Looked Seninole soybeans have an excellent flavor, texture and appearance*

WINTER HAVEN, FLA. The Fifty-Sevonth Annual Meeting of the Florida
State Horticultural SooiEty is scheduled to be hold here Ma1y 16-18, according
to recent announcement of B. F. Floyd, Secretary. Opening session of the
Society will be held on the evening of the 16th with Harold Mowry, Director of
the State Experiment Station as the principal speaker. The entire field, of
the citrus industry will be explored in discussions on Wednesday and Thursday.
The Vegetable Section of which Dr. F. B. Jamison is Cheiteanj will hold its
sixth annual session on Wednesday afternoon and Thursday morning. The Krome
Memorial Institute with Dr. H. S. Wolfe in charge will also meet at the same
time. F. M. O'Byrne of Lake Wales, president, will be in charge of the
Society programs.
