PARK AND CEMETERY.

that he was disposed to transfer it to 
the city through the committee be- 
came known and a number of lumber 
men made an offer that was so much 
better than that of the park commit- 
tee that the holder felt obliged to sell. 
The pending transaction came to 
the ears of some Denver men and 
they visited the owner and urged him 
to let them take it at an advanced 
figure over that offered by the timber 
men. Finally, after a few weeks of 
negotiation, he agreed to the terms 
and the title to the tract, which is 
several hundred acres in extent, was 
passed to the Denver men. 
Now the committee of the Real Es- 
tate Exchange has made an agree- 
ment with the purchasers, that, when 
the city is ready to acquire this and 
other sites for park purposes, the 
latter will transfer the property for 
what it cost, with 6 per cent interest 
to cover their expenses and the use 
of their funds for the intervening 
time. Warwick M. Downing, is chair- 
man of the park committee of the 
Exchange. 
The most novel form of advertising 
which Denver has yet received will 
be presented next summer at the con- 
vention of the National Association 
of Real Estate Exchanges in Louis- 
ville, Ky. It will be a topographical 
relief map showing the city, the civic 
center, park systems and boulevards 
and the mountain parks which are to 
be established in the mountains and 
foothills west of the city. 
One of the fine improvements re- 
cently made in the Denver parks is 
the Cheesman Memorial pavilion, 
which stands on the summit of a 
beautiful rise of ground in Cheesman 
Park. The memorial is one of the 
largest marble structures west of the 
Mississippi. It is 113 feet 6 inches 
long, 46 feet 10 inches wide and from 
the foot of the marble base to the 
top of the marble baluster is 27 feet 
2 inches. The roof is of reinforced 
concrete. This roof and the marble 
architraves and pediments are upheld 
on forty-four solid marble columns 
and eight marble piers. These col- 
umns are arranged in pairs around 
the building. With the bases on 
which they stand the columns are 
each 17 feet 2 inches high; the col- 
umns proper are each sixteen feet 
high. Each is built up of ten marble 
sections after the fashion of the old 
Greek buildings. The style is the 
Roman Doric, in which the bases and 
capitals are very plain, and the col- 
umns without fluting. The Chees- 
man Memorial is a gift of Mrs. Wal- 
ter Cheesman, in memory of her hus- 
band. It was designed by Marean 
& Norton, and built by Ladd & San- 
ger, both Denver firms. The material 
for it is marble from the Colorado- 
Yule marble quarries. In front of 
and below the pavilion will be three 
pools of water, each fifty feet by sev- 
enty. Facing the pools, from the 
pavilion side, is a cement wall, 
through which broad staircases lead 
down from the building to the pools. 
Along the face of this wall are 
niches in which will be fountains; five 
in the central panel, in front of the 
middle pool; two in each of the end 
panels in front and one on each cor- 
ner. Four of these will be plain, the 
others will discharge water into the 
basins through classic masks of ce- 
ment. Fountains will spring from 
each of the pools and between them 
are walks. 
SURFACE TREATMENT OF WASHINGTON PARK ROADS 
From an address before the American Association for the Advancement of Science. 
By Spencer Cosby , Colonel U. S. Army, In Charge of Office of Public Buildings and Grounds 
Our method of applying oil to 
macadam roads in the Washington 
parks is as follows: 
All ruts and holes in the surface 
of the road are first repaired by clean- 
ing out the cavity, filling it with 
coarse stone, which is covered with 
a coating of hot, heavy, asphaltic oil, 
then sprinkling a light coat of screen- 
ings over the oil, and finally compact- 
ing the mass by ramming. When all 
holes have been repaired, the sur- 
face of the road is thoroughly cleaned 
with rattan brooms, care being taken 
to remove all loose materials and 
caked dirt or dust so that the stone 
forming the wearing surface of the 
road shall be exposed and clean. 
When the road is entirely free 
from moisture, and during warm, dry 
weather if possible, a light asphaltic 
oil is spread, without being heated, 
over its surface by means of special 
sprinkling wagons. One-third to 
one-half gallon of oil to the square 
yard usually forms this first applica- 
tion. To allow it to penetrate into 
the surface, the road is closed to 
traffic for at least 48 hours after the 
first application. 
At the end of this time the surface 
of the road is covered with a thin 
coating of clean, coarse, sharp sand 
or broken stone screenings, free from 
dust; it is then rolled and traffic al- 
lowed to go over it. 9 cubic yard 
of sand or screenings usually covers 
from 75 to 125 square yards of road 
surface. 
In this climate and under the con- 
ditions of traffic obtaining on our 
park roads, the oiling treatment de- 
scribed above keeps the surface in 
excellent condition for a year. It is 
never dusty and is only muddy when 
for a few hours, after a heavy thaw, 
the skid chains of automobiles tear 
up the surface. The subsequent pas- 
sage of automobiles without chains 
soon irons out the roadway. At the 
end of the year the surface of the 
road is again thoroughly cleaned; 
from one-fourth to one-sixth of a 
gallon of oil to the square yard under 
normal conditions is spread over it, 
and the road closed for 48 hours and 
covered with sand or screenings as 
before. This treatment is continued 
from year to year. 
Instead of handling the oil in bar- 
rels, we have found it much cheaper 
to buy it delivered in tank cars, from 
which it is unloaded into the sprink- 
ling wagons. A pressure-tank wagon 
was used to advantage for the first 
application of oil to the road sur- 
face, but ordinary sprinkler wagons 
with an oil distributing attachment 
and a squeegee fixed behind the dis- 
tributor were found more economical 
and equally efficient in spreading the 
oil the second year. To ensure coat- 
ing all parts of the road with an oil 
layer of uniform thickness, men with 
stiff brooms followed the sprinkler. 
The following are the specifications 
under which we have been purchas- 
ing asphaltic oil for the surface treat- 
ment of park roads: 
1. The oil shall be a viscous fluid 
product, free from water and showing 
some degree of adhesiveness when 
rubbed between the fingers. 
2. It shall have a specific gravity 
of not less than 0.940 at 25 degrees 
C. 
3. It shall be soluble in carbon 
bisulphide, at air temperature, to at 
least 99 per cent, and shall show not 
over 0.2 per cent of inorganic mat- 
ter insoluble. 
4. It shall contain not less than 3 
per cent, nor more than 10 per cent, 
of bitumen insoluble in 86 degrees 
paraffin naphtha at air temperature. 
5. When 240 C.C. of the oil is
