\Ye have used calcium chloride for sev- 
eral years in winter to keep down dust on 
paved streets. Our method is to dissolve 
the material in tanks which are equipped 
with steam coils to heat the water and 
then run it onto paved streets with our 
ordinary sprinkling wagons. With Solvay 
calcium chloride a solution can be made 
that will not freeze until the temperature 
reaches 50 degrees below zero. For tem- 
perature at zero we use a solution of two 
pounds of calcium to one gallon of water, 
increasing or decreasing such quantity to 
suit temperature so that at 20 degrees 
above zero one pound per gallon would be 
sufficient and at 20 degrees below three 
pounds per gallon. The mixture can be 
made in a sprinkling tank by running a 
live steam hose into the tank and stirring 
thoroughly, breaking the calcium as small 
as possible in the first place. An applica- 
tion should last from three to six days, 
but climatic conditions may effect a good 
deal; for instance, if the atmosphere is 
very dry and there is considerable wind, 
the application will dry more quickly, 
whereas, if the atmosphere carries mois- 
ture, the application will absorb a great 
deal of it and retain its efficiency for a 
long period. I could see no benefit in using 
the calcium in non-freezing weather when 
water can be used. Our method during 
open season is to flush our paved streets 
with power flushing machines regularly.

Calcium chloride is the best and only dust 
layer for cold weather that 1 have ever 
used and it has proven very satisfactory. 
I have never used calcium chloride on any 
paved streets in summer time. I only use 
it in fall and winter for laying dust. The 
amount to use depends on the weather. 
When the weather is about zero it takes 
one drum to a 600-gallon tank of water. 
The drum contains about 7C0 1 pounds. It 
will hold the dust for about three days. 
If the weather is cold, more must be used.

Regarding calcium chloride for brick 
pavement, beg to advise that this is no 
treatment for brick pavements. Calcium 
chloride applied on such pavement would 
last only a very short time, besides being 
very expensive. We tried this only one 
time in our downtown section, but found it 
too expensive for the good derived from 
same. We use nothing on brick pavements 
to lay the dust except water.

PARK SUPERINTENDENTS AT SAN FRANCISCO 
The seventeenth annual convention of the 
American Association of Park Superin- 
tendents will be held in San Francisco, 
August 18, 19 and 20. 
The opening day, August 18, will be 
devoted exclusively to business sessions, 
morning, afternoon and evening, while the 
two succeeding days will be given over to 
inspection tours and social functions. 
Inasmuch as the Society of American 
Florists and the National Association of 
Gardeners have set their convention dates 
for the same week in San Francisco, the 
three organizations will undoubtedly bring 
Milwaukee’s new county park commis- 
sion laws will be of interest to park men 
who have noted the encouraging growth 
of the county park and state park ideas in 
recent years. 
The total acreage thus far purchased by 
the county on the recommendation of the 
County Park Commission is 240, the total 
consideration of which is $112,000. 
The City Council has allowed $6,000 for 
the puroose of having a comprehensive 
plan of a future park and boulevard sys- 
tem laid out. During the past two or 
three years Milwaukee has paid a great 
deal of attention to children’s playgrounds 
ami neighborhood centers. This one fea- 
ture seems to take better and is appreciated 
by the masses more than the larger parks. 
The functions of the Board of Park 
Commissioners are to maintain and im- 
prove all park lands and park plots of all 
boulevards which the city acquires. 
The total park area of the city of Mil- 
waukee at the present time is 952 acres. 
together a tremendous gathering of men 
engaged in these professions. 
The Park Superintendents' Association, 
in an effort to have as many as possible 
travel westward together, is arranging for 
a special train from Chicago through to 
San Francisco via the Pacific Northwest, 
which is conceded to be a scenic wonder- 
land. 
The party will assemble at Chicago on 
August 8 and stopovers are planned at 
Minneapolis, Glacier National Park, Spo- 
kane, Seattle, Tacoma and Portland, where

The amount available for operation and 
maintenance and new construction work 
cannot exceed .71 of a mill, which at the 
present rate of taxation amounts to ap- 
proximately $350,000. Of this $350,000, .2 
of a mill, or approximately $100,000, must 
be used exclusively for construction work 
on the lake shore drives which have been 
granted to the city of Milwaukee and the 
United States government. 
In 1897 the state of Wisconsin granted 
to the city of Milwaukee the right to fill 
in Lake Michigan and create a lake shore 
drive from the north limits of Lake Park 
to the south line of Wisconsin street, a 
distance of 15,500 feet, and the government 
granted a similar permit. The Board of 
Park Commissioners is now engaged in con- 
structing that portion of the shore drive 
lying between the Milwaukee River flush- 
ing tunnel inlet and Wisconsin street. Four 
thousand nine hundred and eighty feet of 
breakwater have been constructed and ap- 
proximately fifty acres of submerged land 
provided by local authorities at no ex- 
pense to the party except at the National 
Park. Members and friends and relatives 
of kindred societies will be invited to join 
the party. No specific return route is be- 
ing planned, as the length of time to be 
spent at the San Francisco and San Diego 
expositions is so much of an individual 
matter dependent on time and means and a 
return route via Colorado or the South is 
an open question for individual decision.

tary Roland W. Cotterill, Seattle, Wash.

has been reclaimed. The total cost for 
making this land and puffing the same in 
park shape to the present time is $130,000. 
The state of Wisconsin and the LJnited 
States government also granted to Milwau- 
kee the submerged land off the shore of 
Lake Michigan, 1,000 feet in width; extend- 
ing from Russell avenue south to the 
southerly city limits. This is in the south- 
ern portion of the city. The distance from 
Russell avenue to the present southern 
limits of the city is 6,500 lineal feet. Up 
to the present time 2,600 lineal feet of 
breakwater have been constructed at a cost 
of about $100,000. In 1913 the Board of 
Park Commissioners caused a forestry bill 
for the care of city shade trees to he 
passed, but on account of a legal defect 
the bill could not be made operative. It is 
intended to have this bill remedied so that 
this work can lie started. 
In the operation of the public parks, 
especial care is taken to make the same as 
useful and entertaining as possible to the
