longer be US 'd without burning. Press a soft towel againet the 

 parts, so as to absorb the water, and avoid rubbing; then apply 

 a rather strong solution of strong navy, or plug chewing tobacco, 

 on the poisoned places, and let it dry. The solution is best when 

 the water is hot. I have tried it, and have been cured, or very 

 nearly so, in two days — four days at the most." For another 

 cure see Boston Pinks. The woodbine {Ampelopsis quinquefolia) 

 is often mistaken for tliis plant, but the two may be readily dis- 

 tinguished by observing that a woodbine leaf has five oblong 

 leaflets, while the leaf of the poison ivy has but three. The 

 poison ivy "should not only be known to the farmer, but dili- 

 gently expelled from his premises," {Darlington.) 



Order 11. LEGUMINOUS PLANTS — Leguminos^. The 

 members of this family are very generally distributed throughout 

 the world. It numbers about 6500 species. It is one of the most 

 important orders, whether we regard the beauty or the utility of 

 the species embraced in it. Among the more useful plants may 

 be mentioned, peas, beans, clover and lucerne. Many species are 

 important in medicine. Indigo is obtained from one species. 



28. Rabbit-foot or Stose Clover — Trifolium arvmse. Annual. iS/fm two to ten inchea 

 high, much branched. Leaves composed of three narrow leaflets, on shirt, hairy stalks. 

 Flowers in oblong or cylindrical heads, which become very soft, silky and of a grayish or 

 redish color. 



A naturalized species from Europe, frequent in dry, barren soil. 

 "Its presence is a pretty sure indication of a thin soil, and neg- 

 lected agriculture ; and the appropriate remedy is to improve 

 both." — {Darlington.) 



Order 12. ROSEWORTS— Rosace.-e. Another largo and im- 

 portant family, producing many valuable fruits, and many plants 

 cultivated for ornament. It numbers about one thousand species.

 inches long. Stem twelve to eighteen inches high, somewhat hairy. Rarlkal liaves in- 

 terruptedly pinnate, four to six inches long, terminal leaflet large, roundish and lobed.
