care of trees for streets and parks has been placed under the 
supervision of an experienced official, who superintends the work 
for the entire city. This method is bringing about much better 
results, and is to be recommended wherever practicable. Every 
city should take some action to encourage more uniformity in the 
matter of planting trees. Trees for any given street should be 
of the same variety, equally spaced, planted the same distance 
from the sidewalk, pruned to the same height and kept in a 
healthy condition. They should be free from the ravages of 
horses’ teeth, the old-time ‘‘tree pruner,’’ the merchant’s sign 
poster, and the telephone lineman—the worst pests of street trees. 
A city with beautiful avenues, lined on either side with such 
trees, possesses an asset of almost inestimable value, for it con- 
tributes to the happiness and eivie pride of all its people and 
hence elevates the tide of life through an appreciation of the 
‘beautiful. 
Trees for parks should represent all the varieties possible in 
as nearly as practicable their natural forest habits. A native 
wooded park is an asset which no city or town can afford to con- 
sider lightly. One of the most delightful spots in all Texas is 
to be found in beautiful Brackenridge Park of San Antonio. 
This fine tract of native woodland, generously donated to that 
city by Mr. George W. Brackenridge, will become a priceless 
heritage as the years go by. If the wishes of the former philan- 
thropic owner and lover of nature are observed, it will never be 
defiled by ax or saw, but will remain forever to inspire in the 
hearts of men a love and reverence for the passing things of 
wild free nature, as they come down to us undefiled by the hand 
of man. What better gift could be bestowed by any philan- 
thropist than this, and what better precedent might be followed 
by others. 
THE NAMES OF PLANTS 
Plants, like everything else, are given names by which they 
may be designated. We recognize plants both by common and 
scientific names. The common name of a plant is the name by 
which it is known locally, and frequently differs in various see- 
tions of the country. The co-called Texas long leaf pine of East 
Texas becomes the Georgia pine further east. In fact, this one 
pine is known by as many as thirty different common names in
