 thicker paper and of attractive colors, having 

 covers about twelve and a half inches long by six 

 and a quarter inches wide and then folding them 

 in the middle.

 prints are very attractive and will add much to the 

 interest of your booklets.

 your booklets are made, so that these pressed 

 specimens will be a part of the completed book- 

 let. For pressing such flowers very likely it will 

 be possible to obtain some of the thick botani-
