acquainted. The first part contains all that is necessary for the student. _ 
to know before entering upon practical botany, after which only more — 
extensive works can be read with profit. In the second part the true ~ 
order of Nature seems to have been arrived at. The tables of analysis 3 
and arrangement of the Natural Orders are such that one can scarcely 
fail to be led at once to the object of his search. 
The individual descriptions also seem to secure scientific accuracy 
without that abbreviated and almost algebraic style too much in vogue 
in elementary works. And I cannot doubt but that for your labors you 
will receive the encouragement and thanks of both the practical botanist 
and the beginner, to whose pleasure and profit you have so eminently 
contributed. Very respectfully yours,

I regard Wood’s Botany as a work exhibiting great labor, careful re- 
search, illustrating the principles of botanic science in a clear, correct, 
concise and interesting manner, combining, in a happy degree, correct- 
ness and fullness of description with brevity and perspicuity of language, 
» and in a manner calculated to engage the attention and memory of the 
student in botany ; in fact, supplying a want which has long been seri- 
ously felt by those commencing the science. 
From Horace Silsbee, A.M., Principal of Blue Hill Academy, Me. 
I have omitted no opportunity to recommend the “ Class-Book of 
Botany,” and to explain its superior merits. Its scientific classifications 
and copious and discriminating descriptions of species are qualities 
which not only facilitate an acquaintance with the science, but also ren- 
der it very improving as a means of mental discipline.

Messrs. CrocKER & BrEWSTER—I have used Wood’s Class-Book of Botany, with classes 
pursuing that study, for two seasons. The briefest experience in conducting a class with that 
work, will be sufficient, I believe, to convince any one of its superiority to the school manuals 
on the subject, previously in use. 
he first edition accomplished an important service, in the matter of guiding one from the 
artificial to the natural system. A still more important work has been accomplished, in the 
second, in the construction of synoptical tables, by which the learner passes to a knowledge of 
the natural and only philosop il system, without the machinery of the artificial. Its descrip- 
oes xa 
tions are clear, distinguishing ficiently full. It is THE “‘ Class-Book of Botany.”

From Dr. Young, State Botanist, Bangor, Me. 
“ Wood’s Botany, last edition, is the best in use ;—a very excelient work.” 
From Dr. 8. B. Mead, Augusta, Iii. 
With your Class-Book I am much pleased, and would recommend it to Botanists in the 
Northern, Middle and Western States, as a valuable work, containing descriptions of all the 
plants hitherto detected in those States,in a cheap portable form. Such a work is much needed 
in the West, and I trust will have a large circulation. : 
WILL BE PUBLISHED IN THE ENSUING SUMMER, 
FIRST LESSONS IN BOTANY ; 
Designed for Common Schools, &c., throughout the United States—by the author of the 
“ Class-Book of Botany.’”? This little work will contain, in the form of questions and answers, 
most of the elementary principles of Botany, expressed with as much clearness and ‘simplicity 
as the case will admit oe It will thus be adapted to the comprehension of children at a com- 
ively early age, and is calculated to awaken in them habits of investigation, and an abiding 
interest in this most delightful science. The systematic part will conduct the pupil, by easy 
steps, to an acquaintance with the NATURAL System of Classification, and to the most approved 
methods of Tabular Analysis. A miniature Fiora, containing descriptions of some of the 
most common and obvious plants, both native and cultivated, in the United States, is added as a 
means for preliminary exercises in pergtcal Botany. Thus it will be seen that this work may 
pe ee rded as a stepping-stone to the “ Class-Book,’’ and others of that rank, but never as 8 
substitute for them.—The work will be illustrated with numerous engravings.
