XX PREFACE. 



yet have made Botany a part of their study, to examine well the 

 dissections of the flowers of the grasses which are given in this 

 work, and which accompany each figure, and to compare these 

 with the flowers of the living plants ; and then, by the aid of the 

 botanical description of the plant accompanying each figure, a 

 sound, and not a superficial knowledge, will be obtained ; and by 

 a little perseverance, every species of grass may soon be deter- 

 mined by the botanical description only. 



It is high encouragement to the author, that the important 

 subject of which this work treats is patronized by the illustrious 

 and beneficent Monarch, the King of Wurtemberg ; and His 

 Majesty's gracious permission, to so humble an individual as the 

 author, to dedicate the German translation of this work to His 

 Majesty, must ever continue to excite and encourage him to per- 

 severe in the laborious path of experimental research after useful 

 knowledge. 



The task of translating this work into the German language 

 has happily fallen into the very best hands ; for to superior 

 acquirements in the languages, Mr. Schmidt adds the essential 

 attainment of an intimate scientific and practical knowledge of 

 the subject of the work.
