A bulletin on “ Melaxuma of the English Walnut,” by .H. S. 
Fawcett, has recently been published by the California Horticul- 
tural Commission. This disease causes black cankers and exuda- 
tion of black sap on the large limbs and trunks of English walnut 
trees in Santa Barbara County and certain other counties in Cali- 
fornia. It is infectious, being caused by a species of Dothiorella 
which also attacks a willow in that vicinity, poles of which are 
often used to drop the lower limbs of the walnut trees. If not 
too far advanced, it may be controlled by cutting out the cankers 
and dead limbs and treating the wounds with strong lime-sulphur 
or with Bordeaux paste. 
An important professional paper on “ The Toxicity to Fungi of 
Various Oils and Salts, Particularly Those Used in Wood Preser- 
vation,” by C. J. Humphrey and Ruth M. Fleming, recently ap- 
peared as Bulletin No. 227 of the United States Department of 
Agriculture. The authors conclude that the common molds are 
more resistant to poisons than the true wood-destroying fungi, and 
even among the latter group the different species show a great 
difference in susceptibility. The results of tests on eighteen wood 
preservatives at the Forest-Products Laboratory, against two 
wood-destroying fungi, Pomes annosus Fr. and F. pinicola (Sw.) 
Fr., are given. Preservatives act in a considerably different man- 
ner on these two organisms, the former being, as a rule, far more 
resistant.
