Gives a short account of analyses made of gi'apes and apples to ascertain the amount of 
copper on the fruit. On one sample of the former 0.002 of 1 per cent was found and on 
another no trace whatever. On one peck of apples there was 0.022 cf a grain of copper, this 
amount requiring about2,000 barrels of apples to yield an ounce or the copper oxide. (J. F. J.)

fruit trees with solutions of poisonous substances in order to prevent depredations from

eases.] <Del. Agr. Exp. Sta. Bull. No. 10, Newark, Oct., 1890, pp. 3-7. 
Mentions the results obtained by treatment of vine diseases in the increased money value. 
Notes that leaving unsprayed rows in the center of a vineyard tends to decrease the real 
value of spraying. The unsprayed vines should be outside of all the good influences of the 
sprayed ones in order to obtain an accurate knowledge of the value of the fungicide. Notes 
also that anthracnose can beheld in check by Bordeaux mixture and bv carbonate of copper. 
Argues in favor of using a spray of vinegar to clear grapes of deposit of copper, should it 
be conspicuous (see Exp. Sta. Ree., vol. n, U, S. Dept, of Agr., Washington, Julv 1891 on 
712-713.) (J. F. J.) ‘ ,lj

figs. 4. 
Refers to the diseases of plants investigated by Prof. Chester and mentions the practical 
results of the work in orchards and vineyards. Mentions also investigations made on 
diseases of various field crops. On page 23 refers to studies on copper on grapes and in 
potatoes. Analyses of the former show about 47 pounds of metallic copper in 1,000,000 
pounds of grapes. In potatoes the pulp showed from 1.26 to 1.33 pounds of copper per 
1,000,000 pounds, while the skin showed from 10 to 40 pounds in 1,000.000 (see Chester 
F. D., and Penny, C.L.). (J. F. J.)

for 1890 [Newark], 1891, pp. 129-154. 
On pp. 149-150 discusses copper on grapes and concludes that it is not injurious. The 
tongue is as safe a guide as anything else, as with 47 parts in one million a distinctly metal¬ 
lic taste is perceived; this proportion is the same as that of beef liver. On p. 154 discusses 
the absorption of copper from the soil, and notes that potatoes absorb it to a limited degree 
and that it is mainly stored up in the rind of the tubers. These contain from 16 to 40 parts 
per million, the latter grown in a soil known to be rich in copper. (J. F. J.)

London, Apr. 14, 1891, p. 473, ^ col. 
Refers to an obscure disease due perhaps to overrich soil. Notes that knife pruning fre¬ 
quently causes gumming, and gives as a cure semi-starvation of roots and trimming by 
removing by the finger and thumb branches not wanted. (J. F. J.)

Notes decrease of disease in Michigan, but increase in Maryland. Argues from this that 
benefits are likely to result from enforcement of laws against the disease. States that no 
cure is as yet known. (J. F. J.)

States that while the disease is unknown in England it is common in the United States. 
Refers to work of Dr. Erwin F. Smith, showing contagious nature of the disease. (J. F. J.)

Sandy soil with clay subsoil seems to favor the disease. Caused by soil being too reten¬ 
tive of moisture. Insects have been observed on roots of aflected plants. (J. F. J.) 
1031 . [Anon.] ‘‘Take-all.” <Gard. and Field, vol. xvn, Adelaide, Feb., 1892, p. 
189, col. 
States that fallowed land is most subject to the disease. “Deadheads” considered a 
continuation of “take-all.” Considerable diflereneeof opinion was expressed in a discussion 
of the subject. (J. F. J.)
