skilful gardeners in order to get rid of this pest. 

 One plan is to dress the plants with a very powerful 

 mixture ; the second is to shut the plants up in a con- 

 fined atmosphere, charged with the powerful gases 

 of fresh dung, in a highly fermentative state ; a 

 third, which is perhaps the most reasonable mode of 

 procedure, is to administer successive sy ringings with 

 water heated to 130 degs. 



With regard to the latter operation, a somewhat 

 wider range should be taken occasionally, according 

 to circumstances. The point, therefore, of 130 degs. 

 must be taken in a relative sense ; for instance, for 

 pines in a wintering state, with an average tempera- 

 ture of 55 degs. — say in the beginning of January — 

 130 degs. would in all probability prove fatal. It 

 would therefore appear that, if the scale can only be 

 combatted successfully by a temperature of 130 degs., 

 another season must be sought for the operation. 

 We must honestly confess that we never tried the 

 hot water cure ; nevertheless, under a judicious ap- 

 plication, we should not doubt. 



W^hy, however, not medicate the water? We 

 should certainly add the amount of soft soap which 

 it is known the pine will endure — say rather more 

 than an ounce to a gallon. To revert, however, to 

 the matter of temperature. We would advise the 

 application of the heated medicaments either in the 

 beginning of September or in the early part of April,
