Messrs. H. O. HOUGHTON & Co., of the Riverside Press; design 
publishing shortly a series of sketches of the wild flowers of North 
America, from studies by the well-known botanical artist, Mr. Isaac 
Sprague. Those who are familiar with the accurate work of this skillful 
artist, particularly with his recent illustrations in Mr. Emerson’s Trees 
and Shrubs of Massachusetts, will welcome the promised plates. Each 
portfolio of four colored plates is to be accompanied by descriptive 
letter-press, in which the more interesting details of structure and the 
habits of the plants will be explained.
