seve) HEARTNUTS. ; 
The heartnut,at least the varieties we have tested so far 
have proven perfectly hardy here,as regards winter cold. 
Please do not confuse the freezing of the new folliage of any 
of the nut trees by late spring frosts,with lack of hardiness, After. 
many years of observation, tae wreivtter hes become convinces taat none 
of the walnuts and hickories have any appreciable degres or harciness 
againss the freezing of the new folliage by a hard frost after Shs 
new ieaves are ous. Sur native wiid niclories,butternmuts and o1.acke 
Walmzts will suffer just as badly as will the heartnuts or Persian 
walnuts,if located in an equally exposed location and the leaves 
are advanced to the same degree, Such frost:injury will very likely 
destroy the nut crop for that year,out unless repeated two or three 
times the same spring, will do little iniury to the treese 
It is advisable to avoid frest oockets with all types of nut 
trees,bécause of danger of losing the nut crop by late spring frosts. 
Howevér,many will find that they nave 1ittle or no choice in this 
matter and they may wish to grow nub trees. To these I wish to say 
thet I do not consider the danger orohibitive,you may lose only an 
accasional nut cropand olmost assuredly you will not lose the crop 
every year from ‘frosts, Slack walmats are the best’ bets in these low 
places,because they leateout Tater than most of the other species»

As to the butternut curculio problem with the heartnuts and the 
Persian walnuts. We have found that they can be controled with a come 
bination spray of four pounds of benzene~hexachloride (hexachlora- 
cyélohexane) and four pounds of DDT 50% wettable powder in one hune 
dréd gallona of water. We applied four sprays, one just as the leaves 
separated in the buds,end spray About one week later, 3rd spray about 
two weeks after the 2nd and the fourth spray about the middle of July. 
We had almost perfect control of the curculio on Persian walnuts that 
were quite badly infested the yeer before. The DDT may not be of any 
vyalue in curculio control,but it is well to put it in the, spray as 
4t will control various other types of insetts and certainly does no 
harm in curculio control, For smell amounts of spray,you will have 
to. figure the amounts of materials to use. Behzene-hexachloride is 
sold under various trade names,some of which are as follows; Gamtox 
put out by the California~Spray-Chemical Corp.,Gamex, by the Pemn- 
sylvania Salt Mfg.,Coe, Lexone,by the E.I.duPont de Nemours & Cos3 Ene s 
FODERMAIER~- The nut of this variety is of good size,cracks easily, 
the kernels in large part comming out in whole halves. In flavor it is 
one of the very best. Ripens here in late September or early October, 
Tree grows repidly and bears annually. We have some very fine tree s OF, 
this varlety. : 
WRIGHT We. consider this voriety to be equal in all respects to the 
Fodextinier and to be somewhat hardier, It also ripens itts nuts two 
weeks ahead of .Fodermaier, We believe that this variety will succeed 
anyanore in the United States, We have very fine trees of thie variety. 
A few sample nuts are available, these will be sent out as long as the 
supply lasts. 
The Wright and Fodermaier blossom at the right times to act as 
pollinizers for cach other. Heartnuts will also be pollinized by the 
putternute
