Chinese Cabbage, The. By Dr. Trabut (Rev. Hort. de VAlg., May- June 
1915, p. 69 ; figs.). — The Chinese Cabbage has its reputation still to make in 
Europe, but it is much prized in China, and even Western writers on the 
productions of China pronounce it to be " worth more than all other vegetables 
put together." There are two forms of it grown in China, the Pe-tsai and the 
Pak-cho'i. Some further selection will probably be required to produce a strain 
which can be relied on to heart in the manner of our Western cabbages, but the 
writer of this note points out that it is not fair to reject a vegetable because it 
does not fill the place which we have arbitrarily chosen for it. The Pe-tsai 
is not a variety of cabbage so much as a cardoon, a spinach, and a salad. In 
other words, it is a new vegetable. — M. L. H. 
Citrus Canker. By C. H. Hasse (Jour. Agr. Res. iv. p. 97, Apr. 1915 ; pi.). — 
Warty growths on leaves and twigs of Citrus and Grape Fruit, developing rapidly 
and spreading widely, were found to be associated with a bacterium now called 
Pseudomonas Citri. The organism induced rapid growth of cells in leaf or 
stem which burst through the epidermis and, at first light green, later turn red- 
brown. The cells in the canker tissue become suberized. — F. J. C.

Daffodil Bulbs, Living Pests of. By the Rev. Joseph Jacob (Garden, 
Jan. 2, 1915, p. 4). — There are five : 1, Merodon equestris, the large Daffodil 
fly ; 2, the Swift Moth (Hepialus rigidus) ; 3, Eumerus, the small Daffodil 
fly; 4, the mite ; 5, the eel-worm (Tylenchus devastatrix). The last two are 
best got rid of by soaking the bulbs for twenty-four hours in a 5 per cent, solution 
of copper sulphate. The flies are best caught in nets, and the grubs sought for 
in the bulbs before planting. — H. R. D.

Dried-Fruit Insects in California, Control of. By W. B. Parker (U.S.A. Dep. 
Agr., Bur. Entom., Bull. 235, June 1915 ; 7 plates, 4 figs.). — The most common 
insects attacking dried fruit on the Pacific coast are the Indian-meal moth and 
the dried-fruit beetle. Infestation takes place in the packing- house, the ware- 
house, and the grocery store, the insects finding their way through cracks in the 
boxes and folds of the paper. 
The secret of preparing an insect-free package of dried fruit is to sterilize it 
at a temperature of 180 0 F. and protect it from future attacks by the use of the 
insect-free packing-room, and sealing it in sterile cartons and packages, — V. G. J.
