but is common in the southern part. The tree is usually 0.5-1 dm. 

 (2-4 inches) in diameter and 5-8 m. (15-25 feet) high. 



Distribution. Newfoundland west along the shores of the Great 

 Lakes, south to Florida and west to Minnesota and Kansas. It is 

 frequent in northern Indiana on the wooded dunes bordering Lake 

 Michigan and on the high banks of the lakes and rivers of the 

 northern counties. In the remainder of the State it is usually 

 rare and confined to the slopes of water courses. 



The published records of the distribution are as follows: Cass 

 (Benedict and Elrod) and (Hessler); Clark (Smith); Delaware, Jay, 

 Randolph and Wayne (Phinney); Franklin (Meyncke); Hamilton 

 (Wilson); Jay (M'Caslin); Jefferson (J. M. Coulter); Kosciusko 

 (Clark); Marion (Douglas); Marshall (Hessler); Monroe (Blatch- 

 ley); Noble (Van Gorder); Putnam (MacDougal); Steuben (Brad- 

 ner); Tippecanoe (Cunningham); Vigo (Blatchley); Wabash (Bene- 

 dict and Elrod). 



Additional records are : Putnam (Grimes) ; Tippecanoe (Coulter) ; 

 Brown, Clark, DeKalb, Fulton, Jackson, Laporte, Porter, Steuben 

 and Wells (Deam) . 



Economic uses. Wood very hard, close-grained, strong, reddish- 

 brown. The tree is too rare and small to be of any economic im- 

 portance. The fruit is greedily devoured by birds and rarely is 

 enough ripe fruit found to justify the gathering. 



3. CRAT^GUS.* Thorn Apples. Red Haws. 



Large shrubs or small trees, best at home in a limestone region. 

 This genus has been studied a great deal in this country in the past 

 fifteen years. Much work is still necessary in Indiana since there 

 are a number of other species that belong in this range. 



The '^knob country" and southwestern Indiana are likely to pro- 

 duce the best results.
