TRANSACTIONS OF THE ILLINOIS 



Dr. Edwards — I never saw any trouble with the curculio. 



Wilgus (of Richview.) — Won't it be attacked by curculio here ? 



Walsh — I think it is likely, but at Galena I only found one plum 

 in a basketful that had been attacked. 



Hull — I would call attention in planting plum trees (to protect 

 peach orchards by gathering the curculios to the most natural fruit), 

 to the Columbia variety, whose juice appears to drown the larvse 

 from eggs laid in it. 



Vasey (of Richview) — There are two species of wild plum in the 

 State, the common wild plum (primus Americana), and the 

 Chickasaw (prunus Chicasa). I have seen it in groves in the 

 south part of the State, but am not able to say whether it is intro- 

 duced or native. (In answer to a question). I do not know that 

 there are two species with the peach shaped leaf. 



Pettingill — I think I have had the true Chickasaw; I got it 25 

 years ago under the name of Sugar plum. It sprouts so badly that 

 I should not advise any one to buy plum trees of friend Colman, if 

 they are propagated on the Chickasaw stock. 



Colman — The' stock is a good one, because it dwarfs the plum. 



The sprouts come from the seeds of fallen fruit, rather than from 



the roots. 



Note by the Secretary. — I append a few notes from various authorities, tending to 

 show with .the above discussion : 



1. That the Chickasaw may have many and strongly marked varieties, of which the 

 most striking, common peculiarity is the peach-shaped leaf. 



2. That it grows in a cultivated or adventitious state, nearly or quite to the north line 

 of the State. 



Grey's Manual. — Primus Chicasa Michx. (Chicasa w Plum,) stem scarcely thorny (8 — 

 15 high) ; leaves nearly lanceolate, finely serrulate, glabrous ; fruit globular red, nearly des- 

 titute of bloom (}4 — % in diameter) ; the ovoid stone almost as thick as wide, rounded 

 at both sutures, one of them minutely grooved. Maryland to Illinois (probably not in- 

 digenous) and south westward. 



Browne'' s Trees of America. — A tree of this kind is standing in the garden of Rev. E. 

 M. Johnson of Brooklyn in New York, which has attained a height of about twenty feet, 

 with a trunk of ten inches in diameter. It is perfectly hardy and matures fruit every year. 



Darlington's Weeds and Useful Plants. — Flowers, April — Fruits, July. — This little tree 

 (which we believed to be a native of a Southwestern territory, where it is a small shrub 

 in its wild state,) by long culture, produces a very pleasant fruit. When we consider the 

 the great difficulty attending the culture of the common plum on account of the attacks
