Preface 



The first edition of Beam's "Trees of Indiana" was published in 

 1911. By limiting the distribution, the edition of 10,000 lasted 

 about three years. The demand for a book of this kind was so great 

 that a second edition of 1,000 copies was published in March 1919. 

 This edition was exhausted within five days after its publication was 

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

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

 the school teachers of the State. 



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

 in our public schools, and since a book on the trees of the State is in 

 demand, the Conservation Commission has authorized a revised 

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

 3 of 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 Mr. 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.
