Trees or shrubs, sometines 13 meters (45 feet) high. In the mountains 

 of Vermont the fruit is often abundant, very juicy and sweet, and in 

 much demand both by man and the birds. The berries on the long 

 racemes ripen at different times and are perhaps two weeks in maturing, 

 thus furnishing food for some time. 



3. CRATAEGUS. THORN APPLES. RED HAWS. 



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

 genus has been studied a great deal in this country. 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 produce the best results.
