AME 



name for the Medlar, to which this genus 

 is closely allied. Nat. ord., Appieworts 

 [Pomace<B~\. Linn., 1%-Icosandria 2-Di- 

 2)entagynia.) 



Hardy deciduous shrubs, closely allied to the 

 Medlar. Layers ; common rich loam. Small 

 troes cultivated for their showy white flowers, 

 which are produced early in the season. They 

 are also propagated by grafting on the hawthorn, 

 or on the quince.

AMERICAN ALOE. Aga'vc America'na. 



AMERICAN BLIGHT. The insect attack- 

 ing our apple-trees, and known by this 

 name, is the Eriosoma lanigera of some 

 entomologists, and E. mail and Aphis la- 

 nigera of others. Its generic characters 

 are, having an abdomen (belly) without 

 tubercles, antennae, or horns, short and 

 thread form, and the whole body more or 

 less cottony or tomentose. The presence 

 of these insects is shown by the white 

 cottony matter in the cracks and excre- 



scences of apple-tree branches in the 

 spring. When crushed they extrude a 



reddish fluid. These insects are inju- 

 rious by piercing the sap-vessels of the 

 tree, sucking the juice, and causing 

 wounds which ulcerate, and finally de- 

 stroy, the branch attacked, by corroding 

 through all the sap-vessels. The cottony 

 matter is abundant ; and, wafted to other 

 trees, conveys to them infection by bear- 

 ing with, it the eggs or embryo insects. 

 Such, however, is not the exclusive mode 

 of diffusing the disease ; for, although the 

 females are usually wingless, yet some 

 are probably produced with wings at the 

 season propitious to colonization : the 

 males are uniformly winged. In the win- 

 ter these insects retire underground, and 

 prey upon the roots of the apple-tree. A 

 tree thus ravaged at all seasons will soon 

 be killed, if prompt and vigorous reme- 

 dies are not adopted. The affected roots 

 may be bared and left exposed for a feu 

 days to the cold, and the earth, before 

 being returned, be saturated with arnmo- 

 niacal liquor from the gas-works. In 

 early March the branches should be 

 scraped and scrubbed with the same am- 

 moniacal liquid, or a strong brine of com- 

 mon salt; but, whatever liquid is em- 

 ployed, the scraping and hard bristles of 

 the brush should penetrate every crack 

 in the bark. We have found spirit of 

 turpentine, applied thoroughly to every 

 patch of the insect by means of an old 

 tooth-brush, the most effective destroyer 

 of these insects. The spirit must be ap- 

 plied carefully, because it kills every leaf 

 on which it falls. The codlin and June 

 eating-apple trees are particularly liable 

 to be infected ; but we never observed it 

 upon any one of the russet apples ; and 

 the Crofton pippin is also said to be ex- 

 empted. Our woodcut represents the in- 

 sect of its natural size as well as magni- 

 fied. The head, antennae, and proboscis, 

 by which it wounds the sap-vessels, are 

 still further magnified. 



AMERICAN COWSLIP. Dodeca'theon. 



AMERICAN CRANBERRY. Oxyco'ccus 

 macroca'rpus. Soil light, and occasion- 

 ally manured with rotten leaves. Peat 

 has been considered indispensable by 

 some cultivators ; but we much question 

 whether this be not a mistaken impres- 

 sion, and should not be allowed to deter 

 persons from planting in any ordinary 

 dark vegetable matters, soft alluvium, or 

 humus which may happen to be within 

 reach. On making an artificial compost, 

 we would avdvise one-third peaty or other
