THE PINE-APPLE. 49 



from the laundry, to every gallon of which is added a 

 quarter of a pound of yeUow soap. In»this the plants 

 are immersed, and allowed to remain in it for twelve 

 hours. 



Brown Scale. — This insect sometimes affects pines, 

 but it is not nearly so difficult to deal with as the white 

 scale. I know from experience that syringing with 

 clean water, heated to 140°, completely kills it without 

 injuring the plants. 



Mealy Bug. — This is also a most formidable insect to 

 get rid of when it gets established on pine plants. The 

 white dusty material with which it surrounds itself 

 completely protects it from the influence of hot water 

 applied through the syringe, and it is second in its 

 destructive effects and difficulty of being eradicated 

 only to the white scale itself. If allowed to go on, it 

 affects every part of the plant — the fruit, leaves, and 

 roots. Consequently, the first appearance of it should 

 be dealt with as a serious evil, to be checked and 

 eradicated at once. Mr Tillery, of Welbeck, writing at 

 the same time as that I have already referred to in the 

 case of the white scale, says that he found Scotch snuff 

 applied in the same manner as he recommends the soot 

 and sulphur for scale to completely eradicate the mealy 

 bug. For the destruction of this pest there have been 

 nearly as many receipts published as there are days in 

 the year. I have been fortunate enough to have had 

 no experience in ridding pines of this insect either ; I 

 will, however, quote a receipt from the ' Transactions of 

 the Horticultural Society of London,' which is said to 

 be effectual for the destruction of this insect as well as 

 scale on pines : " To three gallons of rain-water add 

 two pounds of soft soap, eight ounces of sulphur vivum,
