NEW ENGLAND FARMER.

THE PENOBSCOT PLTJM. 



This fniit originated in the garden of James 

 McLaughlin of Bangor, Me., and was intro- 

 duced by B. F. Nourse and Henry Little of 

 Bangor. The illustration was drawn from 

 fruit raised by 'Mr. Henry Vandine of Cam- 

 bridgeport, Mass. 



The tree is a very thrifty grower, bears 

 young, and the specimens we have seen of it 

 have been unusually free from wart or blight 

 of any kind. Fruit largo, about the size of 

 the Jefferson ; oblong, marked with a deep 

 suture ; stem an inch in length, slender, and 

 set in a small cavity ; skin, orange yellow, 

 smooth and fair, with no blush. !Mr. Yandine 

 represents it as among the best, and well 

 worthy of cultivation. 



— The Laconia Democrat says that the ravages 

 of the new cabbage worm were stopped the past 

 season in one place by a liberal coating of fine salt 

 or. tVf "bbageB""" -lornlng while the dew was on. 



COLOR IN" AUTUMNAL FOLIAGE. 



Mr. I. AVliarton, in the Amcnca.n Jownal' of 

 Science observes : — If chlorophyl, the green- 

 coloring matter of leaves, should be lik(> many 

 other greens, a compound color, it must have 

 for one of its elements, a vegetable blue, ca- 

 pable of being reddened by acids. 



If the juices of leaves kept in a neutral con- 

 dition by vital force, or by alkaline matter 

 brought in the sap from the earth, should, when 

 circulation ceases, become acidified i\v tite at- 

 mospheric oxygon, those juices would tlien be 

 capable of reddening the vegetable blue of 

 the chlorophyl. 



If, however, that vegetable blue .should be 

 thus reddened, it ought to become blue again 

 when exposed to an alkali ; or in otlior words, 

 if green leaves should be reddened in llie au- 

 tumn in the manner here suggested, by the ac- 

 tion of the oxydizing atmosphere, they ought
