would either of them be of service, if sprinkled when the dew 

 was on, or on a damp day, so as to adhere to the leafage. 

 As the insect was observed by Mr. Sym Scott to feed during 

 the night or when the leaves were moist, the time chosen for 

 dressing should correspond. The proportions of the above 

 mixture are as follows : — One bushel of gas-lime, one bushel 

 of lime fresh from the kiln, six pounds of sulphur, and ten 

 pounds of soot, well mixed and powdered. To be applied 

 early in the morning. The above is enough for two acres, 

 and a broadcast machine is recommended as an expeditious 

 way of spreading it. Dressings of guano and salt, or of any 

 chemical manure suitable for running on good growth would 

 be of great use during attack, which if it occurs at all is apt 

 to be severe. 



There does not appear to be any reason to suppose that 

 this attack affects other field-crops than Beet or Mangold, 

 although in one instance annual weeds consisting mainly of 

 Cbickweed were attacked in the infested field. Turnips and 

 Carrots on the two sides of infested Mangolds escaped injury, 

 and, judging from what has been recorded before, there would 

 be no reason to fear danger to other crops put into infested 

 ground, even when attack was known to be present, or 

 immediately after attack. Besides Turnips and Carrots above 

 mentioned, Parsnips, Potatoes, Peas, Beans and Cabbage 

 have been recorded as all succeeding perfectly ^on land where 

 the Mangolds had been destroyed. 



The Silver Y Moth. Plmia gamma, Linn.

Moth, caterpillar, and pujia in cocoon. 



This moth seldom causes much injury in England, but as 

 it is always more or less about during the summer and 

 autumn, and sometimes appears in vast numbers, it is 

 desirable to notice it.
