side, forming a large pad, as in the Thrushes. In this respect the Shrikes 

 resemble the Turdinse and Sylvianse, much more than the Flycatchers, of 

 which the inferior laryngeal muscles are small and blended. The bronchi 

 are moderate, of about 12 half rings.

 — Dicecia Hexandria, Linn.— Asparagi, Juss. 



This species of smilax, which is common along fences, in old fields, and 

 by the borders of woods, is characterized by its shrubby stem, round branches, 

 roundish-ovate, acuminate, slightly cordate, five or seven-nerved leaves, and 

 spherical berries. It flowers in May and June. The berries are of a dark 

 purple colour. 



The Field Mouse. 



This species is found in all parts of the United States, living in the 

 meadows and woods. It forms narrow subterranean passages, to which it 

 resorts on the least appearance of danger, but from which it is easily driven, 

 by thrusting a twig into them.
