however, that he suspects that more than one species of Anthomyiid 
is concerned in this work. 
The rearing of the adult insect which does this damage at the Isle 
of Shoals becomes, therefore, of considerable interest, since H. nigres- 
cens Rnd. does not occur in this country. It may turn out to be one 
of our native species, or it is possible that it has been imported from 
England, perhaps by way of Canada. No remedy beyond burning the 
infested plants with the contained larve has been suggested. 
APPLICATION OF SULPHUR FOR THE RED SPIDER. 
At the February 8, 1894, meeting of the California State Horticul- 
tural Society Mr. Alexander Craw read an interesting paper upon the 
Red Spider in which he announced that Mr. George Ditzler, of Biggs, 
Butte County, Cal., has constructed a broad-cast seeder in such a way 
that it distributes sulphur in a dense cloud over from three to six rows 
of trees in the time necessary to drive through. The sulphur is thrown 
in one direction and is applied in the morning when the leaves are 
damp. An almond orchard treated in this way for two seasons re- 
tained its leaves until late in the fall, whereas other orchards in the 
same district not treated dropped their leaves in August and Sep- 
tember. 
RUSSET ORANGES. 
A little item in the New York Confectioners’ Journal, in which golden 
russets and small dark russets are incidentally stated to be the best 
keeping oranges, has called to our mind a very general experience 
which we have never seen referred to in print. We buy for our own 
table consumption russet oranges in preference to bright oranges, and 
yet in our official work we are in constant receipt of requests from 
orange-growers for methods of destroying the Rust Mite. The harden- 
ing of the skin of the orange from the work of the Rust Mite undoubt- 
edly keeps them juicy, improves them for shipment, and retards decay. 
The selection of bright oranges was a fad among growers and whole- 
sale buyers which did not last. The time has come when russet oranges 
for shipment command higher prices and when remedial treatment for 
the Rust Mite is only necessary for a great excess of this Acarid. The 
change in public opinion in this matter shows that utility governs even 
sentiment. 
DOES THE HORN FLY ATTACK HORSES? 
In our experience with the Horn Fly we have never known it to 
injure anything but cattle. We have several times met stock-raisers 
who believe that they have seen it attacking horses, and Mr. J.S. 
Johnson, of Cheyenne Wells., Colo., writes us under date of February 
27 that he found this species in numbers upon a three-year old horse 
in Cheyenne. Have other correspondents observed similar cases?
