The eggs are deposited on the

The blisters are most prevalent in 

 September and October, and are occa- 

 sionally found on those of the Alex- 

 ander and Parsnep. 



TEPHROSIA. Twenty-eight spe- 

 cies. Stove and green-house evergreen 

 shrubs, and a few herbaceous peren- 

 nials of the latter species. T. virgini- 

 ana '\s half hardy. Seeds or young cut- 

 tings. Loam and peat. 



TERAMNUS. Two species. Stove 

 evergreen twiners. Cuttings. Loam 

 and peat. 



TEREBRATION, or peg-grafting, is 

 an obsolete mode, in which a hole 

 was bored in the slock, and the scion 

 was cut in a peg form to fit iti See 

 Grafting. 



TERMINALIA. Fifteen species. 

 Stove evergreen trees and shrubs. Ripe 



water, thrown over the trees with a 

 garden-engine, will destroy them. 



" Some persons have employed lime- 

 water with complete success; about a 

 peck of lime to thirty gallons of water; 

 and if two pounds of soft soap be added, 

 it will improve the mixture. 



" The best periods for applying these 

 liquids, are before seven in the morn- 

 ing and after five in the evening. The 

 syringing should be repeated until the 

 trees an; free from the slug worm ; they 

 may afterwards be washed clean with 

 pure water; and if the lime water be 

 used in the evening the cleansing may 

 be deterred until the following morn- 

 ing." — Gard. Chron.
