ject of ‘The Weevil,” meaning, presumably, the “‘ Fly Weevil,” ot 
Angoumois Grain Moth (Gelechia cerealella.) The author falls into the 
common error of considering that it is necessary for the moth to punc- 
ture the grain to oviposit, and that consequently this must be done 
when the corn is * in the milk,” considering it to be unproven that the 
insect will propagate in hard corn. Nevertheless, his experience is in- 
teresting as showing that the common practice of pulling fodder in July 
results in preventing the shuck from adhering naturally to and cover- 
ing the ear, thus affording the moths a sure entrance to the grain for 
oviposition. In the same way he believes that the final working of the 
crop in common practice in Florida is apt to produce a similar effect. 
His remarks are based upon three years’ experience, and the sugges- 
tions are certainly worthy of test. 
INJURY TO FOLIAGE BY ARSENITES. A CHEAP ARSENITE. COMBI- 
NATION OF ARSENITES AND FUNGICIDES. 
In Technical Bulletin No. 77b, of the North Carolina Experiment 
Station,* Mr. B. W. Kilgore, assistant chemist of the station, gives the 
results of his investigations of the cause and prevention of injury to 
foliage by arsenites, and of experiments in combining arsenites with 
fungicides. In this work Mr. Kilgore has gone over much the same 
ground covered by Mr. Gillette in Bulletin No. 10 of the Iowa Station, 
and by Mr. Woodworth in Bulletin No. 14 of the Arkansas Station. 
Some of the conclusions reached are as follows: 
That soluble arsenic compounds cause * burning” or “ scorching” to 
foliage, the injury being in direct proportion to the quantity of these 
compounds present. 
That the addition of lime to Paris green or Londou purple mixtures, 
used to prevent this injury may be applied with as great safety ten 
days after as one hour after mixing, because all soluble arsenites in 
London purple and Paris green are changed almost immediately by 
lime into insoluble arsenite of lime. | 
That white arsenic mixture should be permitted to stand for some time 
before application to foliage, for the reason that several days are re- 
quired to completely change it to insoluble arsenite. This change may 
be facilitated by.treating the mixture with boiling water, which fact 
he has utilized in the preparation of a cheap arsenite described below. 
That Bordeaux mixture prevents the solubility of the arsenites by 
virtue of its lime, hence this fungicide may be safely applied in com- 
bination with London purple and Paris green. 
The arsenites combined with Eau Celeste are not safe to use on foli- 
age, because of their solubility in this fluid.

new and cheap Arsenite, and Experiments on Combining Arsenites with Fungicides-
