Preface 



The fii-st edition of Dcam'.s "Trees of Indiana" was published in 

 1911. By limiting the distrilxition, the edition of 10,000 histed 

 abont tlii'ee years. The demand for a l;ook of this kind was so "I'eat 

 that a second echtion of 1,000 copies was pubhshed in Mai-cdi 1919. 

 Tliis ('(htion was exhausted within five days after its i:iul)lication was 

 announced, and thousands of requests for it coukl not be filled. These 

 came from all classes of people, but the greatest demand was from 

 the school teachers of the State. 



Since foifstry is an integral part of agriculture which is now taught 

 in our ])ubli(^ scdiools, and since a book on the trees of the State is in 

 demand, the ( 'onservation Commission has authorized a revised 

 echtion of "The Trees of Indiana." What was formerly Bulletin No. 

 3 f)f the Division of Forestry is now published as Publication No. 13 

 of the Department. The reader's attention is called to a new de- 

 parture in illustrations, which were made from photographic repro- 

 ductions of specimens in Mr. Deam's herbarium. The photographs 

 were taken by Mi-. Harry F. Dietz of the Division of Entomology. 

 It is believed that it will be gratefully received by the public and will 

 stimulate an interest in forestry that should achieve practical results.

 Director, The Department of Conservation.
