OF THE PINE-APPLE.

of which the Pine-plants were taken, should not be 

 used again for that purpose, without first being put 

 into boiling water.] 



The Pine-plants being now ready, let them be 

 put into the mixture, in which they should remain, 

 with every part covered, for the space of three 

 minutes ; then take them out, first letting the tops 

 decline for the mixture to drain out of their 

 centres. The vessel should be immediately filled 

 with fresh plants, and those taken out set in the 

 open air to dry with their roots dow?iwards ; for 

 by placing them in that position the mixture will 

 descend, and penetrate to the very bottom of the 

 leaves in the centre of the plant, whereby the in- 

 sects which are concealed there will be totally 

 destroyed. The mixture will change the plants 

 to a sad green colour, which will give them the 

 appearance of being spoiled ; but as they become 

 dry, they will in a great measure resume their 

 proper hue. 



During the operation it will be necessary to add 

 a supply of hot mixture, in order to keep the 

 whole to a proper degree of warmth, as also to make 

 up the deficiency which must naturally happen. 



If the vessel intended for the mixture be made, 

 as above described, to hold ten or a dozen large 

 Pine-plants at one time, two men will dip and 

 set, &c. about one hundred in an hour, and double 

 that number of the lesser-sized ones. 



It will be proper to do this work in a fine day, 

 and as soon in the forenoon as convenient, that
