216 WISCONSIN AGRICULTUEE.

 we find English botanists still copying the old blunders. Even 

 in the last work of Loudon, it is placed under the name of Cera- 

 sus nigra — the black cherry ! There can be no doubt that the name 

 given by Marshall, and adopted by all American authors, is the 

 proper one — having been first applied.

There are in the United States four different species of native 

 or Wild Plum ; one of them (P. maritima, Wang.) is confined 

 to the Atlantic States ; another, (P. glandulosa, Hooker,) has 

 only been found in Texas ; and the last, (P. chicasa, Michx., the 

 Chickasaw Plmn,) grows as near to us as the southern part of 

 Illinois and the adjacent parts of Missouri. 



11. Prunus Pennsylvania, of Linnoeus. — Bird Cherry. 



The Bird Cherry is not very common with us. It has been 

 detected in the vicinity of Milwaukee ; Mr. John Townley has 

 found it in the interior of the State, and Professor Agassiz car- 

 ried it from the shores of Lake Superior. 



The bark of this tree is, like that of most of the cherries, 

 smooth and brown, detaching itself laterally ; the wood is fine 

 grained, of a reddish hue ; the inferior size of the tree only for- 

 bids its use in the mechanical arts. Of all the American species 

 this one bears the greatest analogy to the cultivated cherry tree 

 imported from Europe, 



In Professor Emmons' very valuable Report on the Trees and 

 Shrubs of Massachusetts, we find it stated that this tree grows in 

 the most exposed situations ; in some parts of Maine and New 

 Hampshire, it springs up abundantly on soil which has been re- 

 cently laid open to the sun in clearing, and especially after it 

 has been burnt over. There is a common opinion among the 

 ignorant that it springs up without seed, in consequence of some 

 action of heat upon the soil. If they would take the pains to 

 examine, they would, however, find great quantities of the seed 

 (or stones as they are called,) just beneath the surface of the 

 ground. This excellent advice of Prof Emmons — to examine
