burning or by j)lo\ving them under deeply. As a rule, 

 insects which chew or suck juices from the leaves of 

 plants, can be more easily controlled than can fungus 

 diseases, which frequently attack the internal tissues 

 of leaves, stems, or roots. 



The cabbage louse {Aphis brassicae) is frequently 

 injurious to cabbages and related plants. The best 

 remedy is a soap solution, made as follows: Into two 

 gallons of water, shave thinly one pound of ordinary 

 huHKhy soap. Boil and stir until the soap is com- 

 l)lotely dissolved, and then add two gallons of cold 

 water. This solution should be thoroughly and forci- 

 bly spraj-^ed so as to completely wet the under sides of 

 all leaves of affected plants. "Black Leaf 40", which 

 is a nicotine extract from tobacco, is effective also for 

 plant louse control. 



(Uitworins of several species are very common. 

 These "worms" feed not only on cabbage and other 

 garden plants, but also on grass and weeds; hence the 

 importance of clean culture with the previous crop. 

 Beyond this, the best remedy is poisoned bran-mash, 

 made by thoroughly mixing while dry either one 

 ounce of Paris green with five pounds of wheat bran, 

 or one ounce of white arsenic with ten pounds of wheat 

 bran, and then stirring in a mixture of cheap molasses 

 and water until the "mash" consistency is reached. 

 Fairly satisfactory results may be had by using the 

 mash along the rows at each plant after the cabbage 

 l)Iants have been set. It is better, however, where 

 thi> ground to be planted was in sod or very grassy 

 during the preceding fall, to take action before plant- 

 ing is done. The soil should be well prepared and 

 thoroughh' disked to remove all green food plants that 

 might compete with the poisoned bait, then scatter at 

 evening, green grass, oats or clover dipped in a mix- 

 ture of one ounce of Paris green in a pailful of water. 

 The baits should be placed at intervals over the bare 

 ground and treatment may be repeated after two or 

 three days and before planting is done. Be careful not 

 to allow chickens to have access to the poisoned mash. 



Cabbage worms, which cause the large holes in the 

 leaves of cabbage and related plants, can be most ef- 

 fectively controlled by spraying or dusting the plants, 

 prior to heading, with arsenate of lead. If applied in
