STREET TREES—VARIETIES 
particularly try to answer the following questions regarding each 
species: 
1. What are its outstanding charactistics? 
2. What are its good points? 
3. What are its defects? 
4. For what conditions is it particularly adapted? 
The note-book should then contain, at the end of this study, 
a series of entries in the following form: 
Street Trees — American elm — Tall, spreading, vase- 
form, branches high, leaving tall clean trunk; varies much 
in form; hardy, withstands wind and drouth; foliage 
good; adapted to city and village streets where plenty of 
room is available. 
Street Trees — Catalpa — Small, and rather irregular, 
low bushy top, hardy, not subject to insect attacks, has 
fine flowers; short lived and poor shade; suitable for 
narrow streets and hard conditions where better trees 
cannot be grown. 
These reports should, of course, be read and criticized in class.
