delicately. (J. F. J.)

Refers to the article in Scientific American (see No. 366), stating that the disease is due 
to starvation. Does not so regard it, but believes lowered vitality may make the tree more 
susceptible to the disease, hence recommends the use of potash fertilizers, especially 
wood ashes, to keep fruit trees in good condition. (J. F. J.)

A supposed new disease has appeared*upon oak trees 2 years old in plantations near Alzey, 
in Rhein-Hessen. The leaves show curled margins and soon fade away, and the branches 
die soon after. In this manner numerous trees have been destroyed, but the nature of the 
disease is not known. Prof. Hartig supposes that the disease is due to a fungus, the myce¬ 
lium of which he claims to have discovered, but not yet described. (T. H.)

Victoria, Bull. No. 14, Melbourne, Dec., 1891, pp. 134-137. 
Notes the occurrence of “yellows” in Victoria. States that he believes it was stamped 
out of bis orchard by digging away the old and substituting fresh soil. Does not know any 
cure and recommends the removal of the tree when the disease has attacked it. For “curl 
blight” recommends, when the tree is coming into leaf, clearing the earth from the collar 
of the tree and watering with 1 pint of coal tar to 6 gallons of water, repeating the same 
when the fruit is set. (j. F. J.)

Gives a statement of the wide extent and destructive character of the disease, advocates 
prohibiting the importation of trees from outside the State, and advises against buying 
trees from localities outside of California. (J. F. J.)

Asks peach-growers whose trees are affected by “chlorosis of the leaves, supposed to be 
the same disease as the American yellows,” to try the effect of mixing sulphate of iron 
with the soil about the trunk of the trees. (J. F. J.)

Refers to work of Dr. Erwin F. Smith, and to the statement of Meehan that Agaricus 
melleus is the cause of the disease. Quotes Sargent against this theory and argues against 
it himself, arguing in favor of a bacillus being the cause. Mentions a disease of the olive 
produced by a similar organism, and one of young blue-gum trees. Recommends the 
immediate destruction of the latter by fire. (J. F. J.)

Refers to an article in Garden and Forest to the effect that the disease in New Jersey is 
caused by a species of root louse and may be cured by the application of kainit or tobacco. 
Questions this assertion and notes that examinations of trees in South Africa have failed 
to reveal any insect or insect injuries. (J. F. J.)

Notes the fact that while peach trees have been shipped in large quantities to the South 
and to the Pacific coast from the Northeastern States, yellows has not appeared in either 
locality. Yet as soon as they were sent to Michigan and some other States the disease 
appeared. Queries why this should be, and refers to reasons suggested in a previous 
number of the Monthly (see No. 679) [i. e., because the disease is due"to Agaricus melleus. 
which does not occur where the disease is absent]. (J. F. J.)

rust had appeared on hop plants. (J. F. J.)
