Sugar-cane Borer. By H.A.Morgan (U.S.A. Exp. Stn. Louisiana, 

 Bull. 70, April 1902 ; 11 figs.). — The larva of the moth Diatrcea saccJia- 

 ralis, does extensive damage to Sugar-cane by boring into the stem. It also 

 attacks Maize and Sorghum. A life-history of the insect in Louisiana is 

 given, and the following remedies are suggested : Autumn planting ; 

 removal of all cane from fields after cutting, and deep burial of refuse ; 

 care in the introduction of new varieties of cane, and the cutting off of all 

 young sprouts from stubble so that grubs with which the sprouts may be 

 infested shall perish by the frost. — F. J. C. 



Sugar-cane, Experiments in Cultivation. By W. C. Stubbs 

 (U.S.A. Exp. Stn. Louisiana, Bull. G6, 1901). — In addition to the record 

 of some results in sugar cane growing, this bulletin contains an excellent 

 summary of some of the reasons for soil cultivation, and the means of 

 carrying out that process to the best advantage. — F. J. C. 



Tent Caterpillar. By W. E. Britton {U.S.A. Exp. Sin. Connecticut, 

 Bull. 139, 7/1902 ; 3 figs.). — The tent caterpillar (Clhiocampa amcricana, 

 Harris) is nearly related to our " lackey " moth, and the habits of the two 

 species are similar. A list of twelve trees upon which it feeds is given. 

 The remedies suggested are the destruction of the egg-mass during winter, 

 Bpraying when Leaves appear with arsenate of lend, Paris green, or Bor- 

 deaux mixture, brushing out the nests with their included caterpillars (an 

 ingenious brush for this purpose is figured) and crushing the caterpillars.

Thunbergia schimbensis. By Spencer Moore (Journ. Bot. its, 

 p. 312 ; 10/1902). Description of a new species, collected by Mr. 

 Kiissner at the Schimba Mountains, British East Africa, from specimens 

 in the Natural History Museum.— (/. S. B. 



Tomato Forcing. By A. C. Beal, B.S. (U.S.A. Exp. sin. Illinois, 

 Bull. HI, Nov. 1902 ; 7 figs.). — The results of some experiments in 

 Tomato forcing for use in winter and spring are detailed. It was found 

 that Tomato plants might be had in fruit 50 days after benching and 

 128 days from sowing. The main points tending to success seem to be: 

 (1) checking the plants by growing in small 3,',-inch pots until ready to 

 plant out, when they should be showing open blossoms and be very much 

 pot-bound. (2) planting so as to allow as much light as possible to reach 

 the plants. (3) hand pollinating. (The pollen is shed only on bright 

 days, and should then be collected and placed on stigmas of flowers. 

 Care in this direction results in the setting of a larger number of fruits of 

 more uniform size.) (4) Careful selection of varieties. 



Plants trained to a single stem gave better results than those trained 

 to three stems, the yield of the former being 1£ lb. per square foot of 

 bench against \ lb. of the latter. The average yield for the winter and 

 Bpring crops was from 2 to nearly 2\ lbs. per square foot of bench, or 

 from 7 to almost 9 lbs. per stem.
