32 PROGRESS OF BOTANY 



Collection of Texan Plants, by Dr. George Engelmann and Pro- 

 fessor A. Gray. 



In this year, also, a " Class Book of Botany' was published by 

 Mr. Alphonso Wood, of New Hampshire ; and two years after- 

 wards, a second much improved edition appeared. The same gen- 

 tleman has quite recently prepared an elementary work for young- 

 beginners, entitled, " First Lessons in Botany." This has been 

 adapted to the present state of the science ; and seems well calcu- 

 lated, both to facilitate the first steps of juvenile students, and to 

 impart correct views of the subject. 



In 1846, Professor A. Gray and W. S. Sullivaxt, Esq., 

 published a beautiful little work on the Mosses of the Alleghanies ;* 

 Mr. Si h levant likewise commenced the publication of Contribu- 

 tions to the Bryology and Wepaticology of North America; and 

 Professor Gray also published Illustrations of New, Bare, or 

 otherwise interesting American Plants, under the title of Chloris 

 Bo re a li-A m erica n a . 



In the same year, appeared a Report on the Trees and Shrubs 

 groiving naturally in the Forests of Massachusetts, by George 

 B. Emerson, Esq., which is a model of its kind, as well for accu- 

 racy of description, as for the amount of authentic information 

 respecting the character, properties, and uses, of the objects de- 

 scribed. 



In 1847, a small volume treating of those plants which American 

 agriculturists are more especially interested in knowing a sort 

 of Practical Farmer s Flora, was compiled by the writer of this, 

 and published under the title of Agricultural Botany. 



In the present year (1848), we have been indebted to Cambridge, 

 Mass., (which seems now to be the chosen seat of the science,) 

 for three admirable botanical works, viz.: l.A Synopsis of the 

 Lichenes of New England, the other Northern States, and British 

 America, by Edward Tuckermax, A.M. ; which will be truly ac- 

 ceptable to those who study that remarkable family of plants. 2. 

 Next, avc have from Professor A. Gray, a thick pocket volume, 

 descriptive of the Plants of the Northern and Middle States, 

 under the title of Manual of Botany. f This is the most complete 



* Mr. Sullivaxt also, about this time, issued some fifty copies of Sets of Mosses, 

 in two handsome quarto volumes. These were not intended for sale, but merely 

 for presentation to the amateurs of Muscology. They contain specimens of 215 

 true Mosses, and 77 Hepaticce, in all 292 ; and are beautifully prepared.
