Elms. In September, 1950, the Director of Maintenance and 
Operation of this Department wrote us the following: 
All trees were in good condition when received ; 
the roots were well protected and still moist. The 
trees were planted in our tree nursery on Riker’s 
Island, the soil consisting of disintegrated garbage 
and ashes, which had been under cultivation for 
about ten years. 
The trees made a reasonable 
past season, but as yet show o/evidence of the 
characteristic upright growing” hahit of the Augus- 
tine Ascending Elm. The,leAves werage about 21% 
inches long and there. ne/appearance of disease. 
In July, 1951, the same #fRtial wrote the following: 
After two years of growth, mos{ of these trees 
are ten feet/iy height and are in a Wgorous condi- 
tion. The new growth produced this season measures 
as muclwas thirty inches. Enclosed you will, 
leaves fwhich measure five and one-half to 
three-quarters inches long. 
ese trees are presently located in our nursery 
and will be kept there until the trunks measur€\three 
to Shree and one-half inches in caliper, after which 
they will be set out in our parks and parkway 
An actual-sized outline of one of the leaves which was Fnclosed 
in this\ letter is traced on this page. The trees by this time 
doubtless show their characteristic up-right form; this form can 
be seeft in the four-year-old trees in our own nursery 
The Trees and Parking Division of the District of Cdélumbia 
purchaged 100, 1 to 114 inch caliper trees in the Spring @f 1950. 
After less than a year of growth in their new location, the Super- 
intendent of this Division wrote to us in February, 195? 
We are extremely pleased with the growth of 
trees we purchased in February, 1950. They al 
look ice and healthy. One hundred were planted oh 
the streets and the only trouble encountered was 
that seyeral were broken off by children because 0;

Most cities prég er to plant their Augustine Ascending’ElIms in 
their own nursePies when they are as young as the W shington, 
D. C. trees were and then to transplant them after 2 gr 3 years; 
buying trees youngtand growing them in city nurséries enables 
the city to save on tkhe-higher costs for largef trees, added

parks, thus eliminating the loss 6f*srowth in the year following 
the second transplanting; an eight-foot white stake or rod, 
driven into the ground near the tree and tied to it will form a 
protective reminder and make the tree secure.
