gcolofiists or iiH'xpci'iciuH'd holaiiists, and when such records are (lues- 

 tioiicd it is done with a spirit of scientifii' accui'acy. Some of our early 

 authors did not (Ustiiifruish ))oiw('en cultivated and native trees, which 

 involvf^s the distribution of certain speckles. 



Tlu^ luiljitat of many si)ecies is discusse(l; which suggests forestal, 

 horticultural and ornamental possibilities. Then too, the habitat of a 

 ti'ee, helps to identify it. When associated trees are given, those are 

 enumerated which are chara(^teristic of the species thi-oiighout its I'ange 

 in our ai't^a. and they are arranged in the order of their abundance. 



A county map of the State is included which will assist in finding the 

 range of each species. A forestal ai'c^a maj) is also added to visualize 

 certain habitats of the State. 



The range antl distiilMition of the species in the State has been given 

 considei'abU^ attention to encourage investigation along this line. 



Kcniarks. — Under this title the economic uses of the ti'ees and their 

 ]ii'oducts have been given. In addition hoi'ticultural and unclassified 

 information is included. 



Illiislralions. — All of the illustrations except two are photographic 

 rejiroductions of specimens in the writer's herbarium. The two (h-aw- 

 ings werc^ used in the first edition. 



About 20 of the photographs wer(> made l)y Paul Ulman, and the 

 remaimU'r by Harry V. Dietz, who has hil^oriously tried to obtain good 

 reproductions fi'oin the material at hand. 



Kxplaiialioii of IMaj) of Certain Foreslal Areas. — In descriljing 

 the distiibution of certain species of trees within the State, it was found 

 convenient to speak of certain foi'estal areas which are here described, 

 and are illustrated by a, ma,]) which may be found at the end of the text. 



Lnkf Rajion: — The southernmost lakes in Intliana are those located in 

 the southwestei-n jiai'l of Wells County; Lake Galacia about five miles 

 northeast of Fairmount in (Irant County; Lake Cicott in Cass 

 County; and Kate's Pond about l.i^ miles northwest of Independence 

 in Warren County. Iloughly estimated, all of Indiana north of a line 

 connecting these lakes might be considered the lake area of the State. 

 Prairie Area: — "While the interior of Indiana, has ciuite a few small 

 areas calletl prairies, the real western praiiie did not extend far into the 

 State. The dividing linc^ is very irregular, and several elongated lobes 

 extended fartlier east than indicated by the map. The larger areas 

 east of (he line were the extensive jn-airie area of the Kankakee Valley; 

 the northei'u part of Pulaski County; and )iarts of White and Tipjie- 

 ca.noe Counties. " Knob" Area: — This is the hilliest part of the State 

 and is local eil in the south-central part. It is contained in the un- 

 ghiciated portion of th(> State, and includes the "knol)s" of the 

 Knobstone, Chester and Mansfield sandstone arcvis of Indiana. In
