often causes it to be preserved, when farms are cleared, for the 

 purposes of shade, being, as one is often told, "good lor nothing 

 else." 



The flowers appear in May, 

 and the seeds are ripe early 

 in June ; they may be then 

 immediately planted. But, 

 the tree is so common in our 

 forests, of all stages of growth, 

 that abundant supplies of 

 young, healthy, and vigorous 

 trees may always be obtained 

 without resort to the seed, or 

 any other mode of propaga- 

 tion. The grow'th, under fa- 

 vorable circumstances, will 

 be about half an inch in di^ 

 ameter each year. 



There is one other species 

 of Elm, first noticed and de- 

 scribed by Mr. David Thom- 

 as, of New York, and hence 

 named Thomas' Elm, {Ulmus 

 racemosa, Thomas,) which 

 ■i may probably hereafter be 

 found in Wisconsin. It is 

 usually confounded with the 

 other kinds, but may always 

 be known by the flowers, 

 which are on pedicels ar- 

 ranged in the form of a com- 

 pound raceme. The branch- 

 es are mostly covered, or 

 winged, with a corky ex- 

 crescence. In other species 

 the flowers are in small clus- 

 HACKBEERY. tcrs, and nearly sessile.
