DESTROYING THE CABBAGE 

 WORM. 



A number of Pennsylvania cabbage 

 growers wrote to Prof. H. A. Surface, 

 the State Zoologist, for instructions in 

 regard to destroying the cabbage 

 worm, which has become quite a seri- 

 ous pest of the cabbage crop. For the 

 benefit of all growers, State Zoologist 

 Surface has given out the following in- 

 formation: 



"The cabbage worm is most easily 

 destroyed by the use of an arsenical 

 application. Most of our successful 

 cabbage growers use about two pounds 

 of arsenate of lead in 50 gallons cf 

 water, or one pound of paris green in 

 the same amount of water. The arsen- 

 ate of lead sticks better than the paris 

 green, especially on cabbage leaves, 

 and is to be preferred. The liquid 

 bearing the poison should be blown 

 well around the cabbage leaves with 

 a good fine spray nozzle, applying it 

 as a fine mist but not in drops. It 

 Sticks much better when put on in a 

 fine mist than when poured on from 

 a sprinkling can or otherwise applied 

 in drops. 



"If it be not convenient to apply the 

 poison as a spray it can be mixed with 

 thirty times its bulk of paris green or 

 air-slaked lime, and applied as a dust. 

 The best resultsi from this will come 

 from making the application in the 

 evening, or in the morning while the 

 dew is on. The use of arsenites in the 

 dust or powdered form is recommend- 

 ed, especially on small premises where 

 the owner does not have a spray pump. 



"There is no need to fear poisoning 

 consumers by applying arsenical poi- 

 sons to cabbage for the cabbage worms. 

 The heads form from the inside and 

 the constant tendency of the growth is 

 to spread or open the poisoned leaves, 

 and thus they are gradually removed. 

 Also a few of the outer leaves are re- 

 moved in preparing cabbage for the 

 table, and thus whatever poison may 

 adhere to it is taken away. 



"I have never known of a case of a 

 person being poisoned by the spraying 

 or dusting of cabbage, and, indeed, it 

 is estimated that it would take two or 

 three hundred heads to carry enough 

 ])oison to have any serious effect on a 

 person. The extensive growers all over 

 this state resort to poison to keep the 

 chewing pests in check, and especially 

 apply this for the green cabbage worm, 

 the same as tor the potato beetle." 



WOOD CONCRETE AND XYLOLITH. 



Under "Questions and Answers" in 

 Die Gartenwelt for August 14, the 

 reader is introduced to materials for 

 the construction of dung bed frames, 

 which have as yet not been greatly 

 employed for this purpose. 



Wood concrete (Hobzbeton) or Xylo- 

 lith is to be highly recommended for 

 forcing frames and pits built partially 

 under ground. It is of unproved dur- 

 ability, since it is unaffected by mois- 

 ture or acids. Edges and corners 

 liable to be damaged by blows must 

 be protected by having sheet zinc or 

 other metal nailed over the surface. 

 Finished Xylolith can be purchased 

 of the maanufacturers of various sizes 

 of plates. The home manufacture of 

 these plates is not to be recommend- 

 ed, as few persons have the necessary 

 high power presses. With the so- 

 called wood cement now much em- 

 ployed in the construction of roofs in 

 Germany upon which roof gardens

 with tough paper, upon which is 

 placed the first coat of the wood 

 cement, then follow one, two, three 

 and four layers of paper, and each 

 gets its coat of wood cement. As a
