THE AMERICAN ELM IN THE SOUTHWEST 
Our native American Elm is still our ‘most beautiful 
and stately avenue tree. This, however, is true only 
when all the trees along the avenue or street are of the 
Same general shape and habit of growth. The best type 
is the- perfect vase-shaped tree with branches well dis- 
tributed. Elm trees grown from seed show much varia- 
tion in shape, vigor, time of budding out, and form of 
branches as slender, graceful, heavy, crooked or weeping. 
Pruning can never make a lot of seedlings uniform. The 
photo on the left shows the extreme variation of four

THE CLASSEN ELMS 
After several years of research, study, and inspection, five superior 
individual elm trees have been selected from among the finer 
old native Oklahoma Elms planted along the streets of Oklahoma 
City. These have been tentatively designated as Classen Elm 
numbers 1 to 5 inclusive. 
We are firmly convinced that superior strains of American elms 
will contribute much toward Civic Beauty and highway im- 
provement. Experiments and studies are under way to improve 
various other trees, fruits and ornamentals. As our contribution 
towards improvement in avenue planting we are not restricting 
the propagation of these five superior strains of elms. The price 
of these trees for one-year buds on transplanted American elm 
stocks is $2.00 each. They are from 5 to 8 feet tall. Only a 
limited number of these trees are available this year. See photos 
of Classen Elm numbers | and 2 shown here.
