CABBAGES, HOW TO GROW THEM, ETC. 21 



their caterpillar state, are the cabbage moth, white-line, 

 brown-eyed moth, large white garden butterfly, white 

 and green veined butterfly. All of these produce cater- 

 pillars which can be destroyed either by application of 

 air-slaked lime, or by removing the leaves infested and 

 crushing the intruders under foot. The cabbage-fly, 

 father-long legs, the mellipedes, the blue cabbage fly, 

 brassy cabbage ilea, and two or three other insect ene- 

 mies are mentioned by Mcintosh as infesting the cab- 

 bage fields of England ; also three species of fungi 

 known as white rust, mildew, and cyUndrosjiorium con- 

 centricum ; these last are destroyed by the sprinkling of 

 air-slaked lime on the leaves. In this country, along 

 the sea coast of the northern section, in open ground 

 cultivation there is comparatively but little injury done 

 by these marauders, which are the cause of so much 

 annoyance and loss to our English cousins. 



THE GREEN WORM. 

 A new and troublesome enemy to the cabbage tribe 

 has made its appearance within a few years, and spread 

 rapidly over a large section of country, in a green 

 worm. This pest infests the cabbage tribe at all stages 

 of its growth ; it is believed to have been recently in- 

 troduced into this country from Europe, by the way 

 of Canada, where it was brought in a lot of cabbage. 

 It is probably the caterpillar of a white butterfly with 

 black spots on its wings. In Europe, this butterfly is 

 preyed on by two or more parasites, which keep it some- 

 what in check; but its remarkably rapid increase in this 

 country, causing a wail of lamentation to rise in a single 

 season from the cabbage growers over areas of tens of 

 thousands of square miles, leads me to fear that it has 

 reached this country without its attendant parasites.
