Judd Co. New York, 



More than fourteen years ago Prof. Husmann published a 

 book on " Grapes and Wine," which attracted wide attention, 

 and, as a guide to the operations of the vineyard, vintage and 

 cellar, written by a practical worker, met a want felt by many. 

 He now embodies, in the present work, not only the results of 

 all his own labors and investigations down to the present time, 

 but the methods and opinions of eminent grape growers in all 

 parts of the countrj'. Thus the work covers a wide range of 

 experience and is adapted to every latitude. It treats of every- 

 thing of importance bearing upon the culture of the vine, 

 and IS a complete guide for novices therein. Special attention 

 is given to the Phylloxera. 



Ninth Report of the State Entomologist on the Noxious and 

 Beneficial Insects of the State of Illinois. Fourth Annual 

 Report by Cyrus Thomas, Ph. D. 8vo. pp.142. Illustrated. 

 Springfield, 111., 1880. Those desiring to identify the species 

 of Locusts found in the Mississippi V.alley, will find in this 

 report a useful series of descriptions and a synopsis by Prof. 

 Thomas. It contains, also, an account of some of the para- 

 sites affecting domestic animals, and a valuable discussion on 

 Cabbage Insects and the remedies to be used against them. 

 The Pyrethrum powder, however, does not appear to have 

 been tested. 



Science. A Weekly Record of Scientific Progress. 4to. 

 pp. 12. John Michels, Editor. New York. Subscription 

 $4.00 a year, in advance. Single copy, 10 cents. This will 

 be a welcome addition to our scientific periodical literature, if 

 it shall take the place in the United States which Nature 

 occupies in England. In presenting immediate information 

 of scientific events, and in affording scientific workers the 

 opportunity of promptly recording the fruits of their researches, 

 it will prove invaluable. Subscriptions should be addressed to 

 the Editor, Box 3838, P. O., New York.

Extracts from Correspondence, 



Ants vs. Cotton Worms,— .4?^^"^. 2<~,th. The 

 ants do not seem to attack the young larvae and 

 eggs of Aletia, which were crowded on the leaves, 

 and yet thc)^ (the ants) swarm under the netting, 

 and eat up pupa3 placed in jars or boxes on the 

 ground. I think this a very fair test of the work 

 done b}^ ants, since with every condition favorable, 

 they fail to clear off young larvae and eggs upon 

 plants, at the foot of which they have very strong 

 colonies. Under the oak tree, I find many leaves 

 (cotton) scorched by the London purple, applied 

 August 23d. I tried application of undiluted 

 powder (London purple), blowing it from the 

 bellows, and taking advantage of the wind, allow- 

 ing it to float in fine clouds through the plants. 

 I notice occasionally the brown swift, ground 

 lizard, running over the ground in the cotton 

 field. To-day one ate two caterpillars which I 

 had knocked off onto the ground,— H. G. Hub- 

 bard, Centerville, Fla, 



August 2-]th. — Several caterpillars dropped into 

 the midst of a very strong colony of brown 

 (stinging) ants, (No. 82), were ver)' quicklj' de- 

 stroyed; some of them made hardly any effort to 

 escape. The same colony was experimented 

 upon in the heat of the day, and four-fifths of the 

 caterpillars escaped. I have been experimenting 

 with an infusion of pyrethrum, made by pouring 

 hot water (not boiling) upon the powder; but find 

 it worthless. 



August 29,1/1. — Experiments made with a colony 

 of brown ants (apparently same as No. 82), by 

 dropping caterpillars in the path of a moving col- 

 umn, resulted in the escape of fifteen; five were 

 killed by the ants. I have several times observed a 

 column of the same species of ant engaged in 

 robbing colonies of the common light testaceous 

 ant, and at such times they are much less inclined 

 to attack caterpillars dropped in their path. I 

 have never yet witnessed the capture of a cater- 

 pillar upon the plant by ants, unless it had 

 webbed up, and was stiffening to form pupa. 

 During the hottest hours of the day the worms 

 were more powerfully affected by the sting of this 

 brown ant, and a greater proportion were cap- 

 tured by them at this time. During the heat of 

 the day I observed that a caterpillar sometimes 

 succumbed after being twice stung. — H. G. Hub- 

 bard, Centerville, Fla.

 4th, (my No. 62,) hatched during the night of 

 August gth. On August loth I mounted twelve of

in feeding them on young aphids from cotton, the 

 bodies of which I crushed. They were very 

 timid, and ate sparingly. The color is silver 

 gray, almost white. August 12th the larvje re- 

 treated to bottom of earth in the bottle, and curled 

 up in clusters. In two or three hours (10:45 A. M.) 

 they had moulted. Their color now changed to 

 a lead color, or mouse color. Immediately after 

 moulting they became very active, climbing all 

 over the sides of the jar. I gave them crushed 

 Phora aleticE, and they sucked the juice readily. 

 They attacked the uninjured maggots, \>\xi were 

 unable to pierce the skin. I preserved several 

 in Wickersheim solution (No. 62, B). I gave them,
