at a moment’s notice. The total mile- 
age of boulevards oiled is 20.2, and 
the. cost of same is $6,313.40, or 
$312.50 per mile. The average cost 
per square yard is $0.0238 against 
$0.0.331 in 1909. 
At Lake Calhoun a path has been 
established along the steep and wood- 
ed bank between the boat dock on 
Lake street and Thirty-fourth street, 
and stationary benches have been 
placed along it. Both features have 
been used and enjoyed by a large 
number of people. Two additional 
boat docks for private boats and 
canoes have been built for service on 
Lake Calhoun. 
The officers of the Board are as 
follows: Wilbur F. Decker, presi- 
dent; Edmund J. Phelps, vice-presi- 
dent; J. A. Ridgway, secretary; C. A. 
Bloomquist (ex-officio), treasurer; 
Chelsea J. Rockwood, attorney; Theo- 
dore Wirth, superintendent; C. A. 
Bossen, assistant superintendent; C. 
T. Booth, supervisor of playgrounds; 
Max Kaiser, forester. 
EXPERIMENTS IN OILING 
Our extent of roadway which we 
oiled is somewhat limited, about a 
mile long, and the oil was put on this 
spring in May. The road surface 
was: of all kinds. We had the hard 
roadway. We had the dust, which 
we did not remove in some places, 
but was filled up with fresh gravel, 
and this was left on account of the 
lateness of the season and opening 
of the park for public use. It was 
not dressed down, as it should have 
been. We used the Standard road oil. 
I don’t know what number, the 60 
per cent asphalt oil and a black heavy 
oil, practically odorless. This was 
put on hot and put on with sprinkling 
cans in a rather primitive way, but 
the result has proved interesting to

us. As has been said, this was put 
on within two or three feet of the 
margin of the roadway and has wholly 
eliminated the dust problem for us. 
The roadway was closed for a few 
days after being spread and was then 
opened at once to the public and 
was not sticky, was not carried into 
the buildings or neighborhood at all. 
It has been packed down by the au- 
tomobile and other traffic that passes 
through the parkway until some por- 
tions of the road, where it was hard 
to start with, are as smooth and more 
polished than an asphalt street. 
Where the fresh gravel was put on, 
which was experimental with us, I 
had some fears that it would not 
work. Of course our traffic there,

the automobiles, would not be as 
great as in larger cities. I judge, how- 
ever, it will apply to smaller park- 
ways where the automobile traffic is 
not too great. We found this fresh 
gravel, which had 10 per cent of sand 
with it and 5 per cent of loam, soon 
began packing and has spread very 
little. There is a small strip of this 
roadway, oiled last winter with some 
kind of oil, and we put no oil on this, 
and we can scarcely tell the differ- 
ence, which indicates that one oiling 
with the heavy oil will be sufficient 
for the year, and perhaps a light 
sprinkling next year will carry it 
through three years. The manager 
for the state of the Standard Oil 
Company told me a few days ago that
