1891, pp. 15.] 
A paper read before the Massachusetts Horticultural Society, March 7, 1891, giving a 
statement of the structure of wood and the manner of healing of wounds. Refers also to the 
manner in which fungous germs lind entrance into the wood and the bad effects likely to fol¬ 
low. (J.F.J.)

Notes that in Ghent the European plane tree sutlers from Glceosporium nervisequttm, the 
leaves falling from its effects early in autumn. Sulphate of copper recommended as a spe¬ 
cific. (J.F.J.)

Gives preliminary note on a disease of poplar timber reported by the Director of the Artil¬ 
lery Arsenal at Naples, caused by a species of Micrococcus. Occurs in boards badly stacked, 
living in the w'ood vessels and causing yellow discolorations, and a final destruction of the 
tracheae. Organism not cultivated. (D.' G. F.)

770. Arthur, J. C. Carnation rust, a new and destructive disease. <(Am. Florist, vol. 
vi, Chicago and New York, Feb. 18, 1892, pp. 587-589, fig. 4. 
Refers to the recent observance of a carnation disease and its wide extent in the United 
States. Cause stated to be TJromyces caryophyllinus. Gives general history of fungus and 
suggestions for treatment. Bordeaux mixture and ammoniacal solution of copper carbonate, 
both effectual remedies. (See also, Cult, and Country Gent., vol. lvii, Mar. 10,1892, p. 188, 
fig. 1; Garden and Forest, vol. v, Jan. 13,1892. p. 18.) (J. F. J.) 
771. Galloway, B. T. Disease of geraniums. <^Jour. Mycol., vol. vi, Washington, 
Jan. 6, 1891, pp. 114-115. 
States the disease is probably due to the presence of a Bacillus. Disease had been produced 
in several instances by inoculations directly from diseased plants. (J. F. J.) 
772. Halsted, B. D. Fungous troubles in the cutting beds. <Gard. and Forest, vol. V, 
New York, Feb. 24, 1892, pp. 91-92. 
States that diseases of various sorts have appeared on cuttings, particularly of the carna¬ 
tion, rose, clematis, passion flower, and chrysanthemum. In’the carnation, due to species of 
Colletotrichum; in the rose, to a species of Glceosporium; in the chrysanthemum, to a species 
of S ptoria or Phyllosticta; in Abutilon, to a species of Colletotrichum , probably identical 
with that on carnation; in nasturtium probably also the same species. (J. F. J.)

Replies to C. D. Wadsworth that if an insect or a parasite is the cause of violets losing 
their leaves, is not that a disease? Mentions effects observed by himself on both violets and 
on celery. Gives method of cultivating the violet. (J. F. J.) 
774. [Meehan, T.] Disease in Clematis. ^Meehan’s Monthly, vol. i, Germantown, 
Pa., Nov., 1891, p. 74, col. 
Refers to disease as probably of fungous origin, and recommends watering with a solution 
of copper, made by dropping pieces of blue copperas about the size of an e<rg in a barrel of 
water. Draw earth away from plant and form a basin, in which pour the solution to insure 
its reaching the “collar” of the plant, the point usually attacked by the fungus. (J. F. J.) 
775. [Meehan, T.] Rhododendron disease. ^Meehan’s Monthly, vol. ii, Germantown, 
Pa., Nov., 1891, p. 72,1 col. 
Refers to yellowing and dropping of leaves of Rhododendron. Thinks it may be due to 
attacks of Agaricus melleus , but more likely to an oversaturated soil. Recommends under 
draining. (J.F.J.)

ommonded. (J.F.J.)
