and refers to the scab described by Thaxter and Bolley. Records Plnsmodiophora brassicce 
Wor.. upon cabbage and radish, and for the first time in America Peronospora parasitica 
DBy., on leaves of cabbage and Hesperis matronalis. Notes also Macrosporium brassicce 
Berk., on cabbage. Cystopus candidus (Pers.) Lev., is recorded as doing damage on radish, 
and a sclerotial disease of turnips and carrots is noticed. A bacterial disease of salsify is 
spoken of as quite widespread in the State and likely to prove very contagious. Botrytis 
parasitica and Urocystis cepulce are reported as doing damage to onions and onion sets.

done in Bull. 70 of N. J. Ex. Sta. (See No. 135). Gives figures of Phyliosticta hortorum Speg., 
on the eggplant, where it causes serious losses, together with Glceosporium melongence\. 
Si. E. Figures, with description Glceosporiumpiperatum E. &.E., and Colletotrichum nigrum 
E. & Hals., and notes a species of Phyliosticta , all three on the foliage of the pepper. Notes 
presence at Piscataway of Septoria armoracice Saec., and liamularia armoracice FI., on 
leaves of horse radish. Discusses diseases of the cultivated hollyhock, Puccinia malva- 
coarum Mont., Cercospora althceina Sacc., and Colletotrichum malvarum (B. &. Gasp.,) South- 
worth. The violet ( V. odorata) diseases are reviewed shortly and mention made of Cercoc- 
pora violce Sacc., Phyliosticta violce DBy., Glocosporium violocB. & Br., and Zygodesmus albi- 
dus Ell. & Hals. The fungi especially troublesome to carnations mentioned are Septoria 
dianthi Desm., and Vermicularia subeffigurata Schw. Cercospora resedce Fckl., on culti¬ 
vated mignonette is mentioned as controlled by Bordeaux mixture. The black knot of 
plum and cherry trees is treated of and reference made to Bull. No. 78 N. J. Agric. Ex. Sta. 
Quotes report of J. M. White who was successful in the*treatment of his Glairgeau and 
Deil pears for leaf-blight and cracking by use of ammoniacal solution, 6 oz. copper carbonate 
in 100 gallons of water. Mr. White estimates the cost of treating an orchard of 100 apple 
trees thirty to forty years old five times with carbonate of copper at about $20. (See Exper.

Exper. Sta., Bull. No. 19, Jan., 1892, Agric. Col., pp. 1-9,11-12. 
Describes disease and gives experiments in inoculation of tomatoes from diseased potatoes, 
and vice versa. Seedlings also experimented with, with rather unsatisfactory results. The 
conclusions are that the blight is due to a bacterium , probably the same as that causing the 
potato disease; that it is also the same as the blight of cucurbits, and can be transferred from 
one to the other, and that spraying with Bordeaux mixture will probably prove a remedy or 
preventive. (See Gard and Forest, vol. V., Mar. 2, 1892, p. 108; Exper. Sta. Rec., vol in

healthy sprouts for transplanting from hot bed, rotat ion of crops, burning of refuse, sparing 
use of barnyard manure, and dipping roots in ammoniacal solution of copper carbonate b£ 
fore storing in bins for winter. (J. F. J.)
