use a solution of one part Canada balsam in from six to eight parts of 
turpentine oil. 
It is perfectly self-evident that any other balsam soluble in turpentine 
oil, i. e.j turpentine, or a resin soluble in it, will answer the same pur¬ 
pose. Any other volatile oil can also be substituted for turpentine oil. 
A DISEASE OF WHITE FIR.* 
By Dr. Hartig. 
• 
A disease of the white fir, which caused very great injuries in the Ba¬ 
varian woods, was discovered by the author, and shows itself in the dying 
of the bark of younger or older twigs and branches, often for over a 
hand’s length. As a rule, the dying extends over the entire circumference 
of the twig, and in consequence the parts of the plants situated above 
this point die in a few years. More rarely the disease is confined to one 
side of the twig, and does not progress the second year, but an out¬ 
growth occurs at the edge of the dead place. In the dead bark there 
develop numerous pycnidia, rarely larger than the head of a pin, which 
rupture the superimposed cork layer. Within the pycnidia arise numer¬ 
ous small, spindle shaped gonidia, which germinate readily. Unfortu¬ 
nately, an acigerous fruiting form has not been found after several years 
of observations and cultures. To be sure Peziza calycina almost con¬ 
stantly produced a luxuriant formation of Apothecia in the immediate 
neighborhood, yet the absolute proof of its connection with the pycnidial 
form was impossible. Until it can be perfectly known the author has 
given this fungus the name Phoma abietina , n. sp.

PREVENTION OF SMUT. 
In the first number of The Journal! we gave a brief review of a 
paper published in the Journal of the Royal Agricultural Society of Eng¬ 
land by J. L Jensen on u The Propagation and Prevention of Smut in 
Oats and Barley.” The interest shown in this paper has prompted us to 
publish a description of Mr. Jensen’s method of treating the grain, and 
it is hoped that the suggestions made will enable the experiment sta¬ 
tions to test the remedy. Mr. Jensen says: 
We have seen that smut can be prevented by dipping the^grain in heated water. 
* * * The grain to be dipped is placed in a shallow cylindrical basket about 12 
inches deep, lined with coarse canvas, and provided with a cover made by stretching 
the canvas over a ring of such a diameter as will pass inside the mouth of the basket.
