er a good chestnut for
this section. The hardy Persian or English walnuts have not been tested
long enough to warrant any conclusion as to their promise for New
Hampshire; one difficulty will probably lie in the fact that the nuts of
some do not ripen properly under our cool, short summer conditions.

Mr. Matthew Lahti of Wolfeboro, New Hampshire, has been experimenting
with various species and varieties of nuts for that section. His
location on the shore of Lake Winnipesaukee undoubtedly presents a more
favorable site for growing certain types of nut plants than exists here
in Durham, or most other parts of New Hampshire. At the present moment I
have on my desk a parcel received from Mr. Lahti containing some fine
specimens of one of the hardy Persian walnuts which he is growing in
Wolfeboro. The unusually warm and dry late summer and fall of this year
have favored the maturity of this walnut. (For a detailed description of
Mr. Lahti's experience with nut varieties, please refer to his paper
printed below.)

Nut Notes from New Hampshire

MATTHEW LAHTI

Not being able to attend the annual convention I thought possibly some
of the members might be interested in the following random notes of an
amateur nut grower.

My place is in Wolfeboro, N. H., which is situated in the eastern end of
Lake Winnepesaukee, 43 degrees, 35 minutes north latitude; elevation
above sea level, 687'. The elevation of the lake is 504'. Wolfeboro is
just about at the northern fringe of the climate where peaches will
ripen, that is during favorable years in favored locations. Improved
varieties of field corn will ripen during favorable seasons. It also
happens to be the northern fringe of the American chestnut, in favored
location. I have discovered a number of saplings that are still alive.
As a matter of fact, three or four years ago I was fortunate in finding
some ripened nuts, but the trees that bore those nuts have since died of
the blight. While a certain variety of old fashioned sweet cherry will
live and bear fruit, some of the recent improved varieties will not
live. Every one that I have planted was winter-killed. The Montmorency
cherry, however, does well. It is also the northern limit of the pignut.
Butternuts do very well.

DDT Dust versus Butternut Curculio

I was prompted to write this note by reading Mr. S. H. Graham's article
entitled "An Experiment with DDT" appearing on page 101 of the 1945
annual report, in wh
