As it boils the liquid will gradually become tliiuner and 

 thiuner, the lime and sulphur dissolving simultaneously 

 to form a deep orange-red solution. When the sulphur 

 has apparently all entered into solution, which may 

 take two hours or more, slake the remainder of the lime, 

 add to it the salt, and pour the two into the lime and 

 sulphur solution. Boil the whole for from half an hour 

 to an hour longer, strain, and dilute with warm water 

 to 60 gallons. Do not let it become thoroughly cold, but 

 spray while yet warm. 



The principal care in making up this wash is to make 

 sure that the sulphur is thoroughly dissolved. Flowers 

 of sulphur is apt to be more or less lumpy, and these 

 lumps are very difficult of solution. The more thor- 

 oughly the sulphur is ground up with water before be- 

 ing boiled with the lime, the less time it will take in the 

 boiling. 



An iron kettle must be used if the boiling is done di- 

 rectly over a fire. A better and cheaper way, whenever 

 a head of steam is available, is to place the sulphur, lime 

 and salt together in a barrel half full of water, conduct 

 the steam through a j>ipe to the bottom of the barrel and 

 boil it for two or three hours, with occasional stirring, 

 to make sure that nothing is settling. If a boiler is con- 

 venient, a pipe must be so arranged as to conduct steam 

 to a number of barrels at once. 



NEAY PEACH SCALE. [Dia.spi.s aniijfjduli Tryon.) 



Note to detect it. — This scale is readily distinguished 

 from the San Jos(^ scale in that the female is a little 

 larger, of a lighter gray color, with the elongated ex- 

 uvial point ridged and located at one side of the center, 

 and the nuile is smaller, elongated, Avith parallel sides 

 and white. The excuvial point is similar to that of the 

 female, but located at the anterior end. A tree badly 

 infested has a white-washed appearance from the color 

 of the male scales. ^Miere onlj females occur, however, 

 a grayish brown appearance is produced. 



It is the habit of these insects to cluster about the 

 trunk and the lower parts of the larger limbs of a tree. 



The original home of this insect is probably either 

 the West Indies or Japan. From its probable West In-
