PARK AND CEMETERY. 
“The Tarvia Modern Pavement” has 
been given. 
In this construction Tarvia enters not 
only into the top surface of the road, 
but is carried down beneath the top 
course. Coupled with the use of Tarvia 
throughout the road is the use of larger 
stone in the second course. Experiments 
with this form of construction through 
the past two years have shown its su- 
periority over other forms where a con- 
siderable amount of traffic of all descrip- 
tions is to be carried on the road. 
Splendid examples of the Tarvia 
modern pavement construction can be 
seen in Massachusetts on Massachusetts 
avenue, in Cambridge ; on Beacon 
street, Brookline, and in Worcester. 
In Canada roads have been built which 
are giving excellent service in West- 
mount; on ihe Victoria pier, Montreal; 
in Berlin, Ontario ; Guelph, Ontario ; 
and Stratford, Ontario. 
The foundation of the Tarvia mod- 
ern pavement is prepared as for ordi- 
nary macadam, but care should be taken 
to see that this foundation is properly 
drained and properly consolidated, for 
the best of surfaces can be destroyed 
by softness and movement below. Upon 
the foundation the base course is laid, 
using a run of crusher stone 3 inches 
to 1 inch in size. Usually a thickness 
of 4 inches, measured after rolling, 
will be sufficient. This course is filled, 
rolled as for ordinary macadam, and 
then has spread upon it inch of 
clean, sharp sand or good gravel. Over 
this, without further rolling, is sprayed 
Tarvia-A to the amount of one gallon 
to a square yard. Another layer of run 
of crusher stone (3 inches to 1 inch) 
is spread over the Tarvia-A to such a 
depth that when rolled this course will 
be two and one-half Inches thick. It is 
then rolled thoroughly with a steam 
roller until the Tarvia and sand are 
drawn up between the stone and until 
this layer of stone is -bedded firmly into 
the stone below. The layer of Tarvia 
and sand holds this course firmly in 
place and cements the top course of the 
road thoroughly to the bottom course. 
A spraying of Tarvia-X, a denser 
grade of Tarvia, is then given to the 
road, using ly^ gallons to the square 
yard, and a thin layer of %-inch stone 
is spread over the surface. Enough 
stone must be used to fill in all the 
chinks of the surface, making it smooth, 
but not enough should be used to leave 
any loose material on the top. The 
road is rolled again until perfectly 
smooth and a final coat of “Tarvia-A,” 
amounting to one-half gallon to the 
square yard, is sprayed on, and the road 
finished by adding pea stone or screen- 
ings and given a final rolling. 
The Tarvia modern pavement is de- 
scribed at some length in order that 
engineers may recognize its novel fea- 
tures and appreciate its merits. The 
thorough incorporation of the Tarvia 
throughout the road insures the binding 
of every part and the elimination of 
the internal friction which is so de- 
structive to macadam roads. To the re- 
duction of the internal friction the suc- 
cess of the “Tarvia Filled Macadam” is 
largely due, and in the Tarvia modern 
pavement this internal movement is re- 
duced to practically nothing. 
The use of large stone throughout the 
road and in the surface layer insures a 
structural strength not obtainable with 
The Milwaukee, Wis., city council 
has decided to buy a stretch of 500 
acres along three miles of the upper 
river for a public park at the cost of 
$1,000,000, the cost to be paid in twenty 
annual installments. 
A federation of associations inter- 
ested in the parks, playgrounds and 
recreation places of Queens Borough, 
Long Island, N. Y., has been organ- 
ized and a committee appointed to 
formulate a plan and scope for the fed- 
eration. It will push the work of ac- 
quiring park and playground lands and 
will pass on the advisability of projects 
presented to it. 
Bonds to the amount of $75,000 to 
bear four per cent interest and run ten 
years, for park and boulevard im- 
provement, have been authorized by the 
Toledo, O., council. 
The care of the California Redwood 
Park has been turned over to the new 
state commission, and the commission 
has already commenced active work in 
improving it. 
Boise, Idaho, hitherto practically a 
parkless city, is waking up to the fact 
and is moving to secure lands for parks 
and playgrounds. 
Billings, Montana, has a new park 
commission. It has had such commis- 
sions before, but lack of funds pre- 
vented park progress. It is now ex- 
pected that the council will make a levy 
for park purposes and work in park 
matters will begin to move. 
The Oliver Machinery Company has 
notified the park board of New Or- 
leans, La., that it will donate to the 
city a tract of land on Cedar street 
for park purposes. The land lies next 
to the lot purchased from the company 
smaller sizes of stone. This strength 
giving principle has long been recog- 
nized abroad, but with a water bound 
macadam it was not possible to use this 
form of construction satisfactorily. The 
anchoring in of the stone in the wear- 
ing course by the sand Tarvia matrix 
now makes the use of the larger stone 
feasible. 
The use of large stone with Tarvia 
also obviates a difficulty sometimes ex- 
perienced in bituminous construction. 
Since the large stone reaches practically 
through the whole depth of the course, 
rolling up of the pavement is prevented 
and the surface remains smooth and 
without hollows under all conditions.

Park and playgrounds. 
The plans of Carrere & Hastings, 
architects, for the development of 
Hartford, Conn., on the “city beautiful” 
idea are attracting much favorable 
comment in that city. The plan states 
that Hartford possesses advantages, 
natural and otherwise, which give it 
90 per cent of the conditions necessary 
to the ideal city. 
By the death of Mrs. Sarah A. 
Holmes, of Marion, O., widow of the 
late Barnabas Holmes, the town comes 
into full possession of what is known 
as the Natural Park, some 15 acres in 
area. 
Mayor S. M. Hoyer has appointed 
the first park commission for Altoona, 
Pa., which was authorized some months 
ago by ordinance. The city already has 
two small and one good sized park, 
with prospects of securing others. 
Under the civic center plan of city 
beautification, the board of appraisers 
of Denver, Colo., has placed a valua- 
tion of $3,523,463.10 upon the property 
to be acquired for the purpose. 
Frederick Law Olmsted, in pursu- 
ance of his idea that every child should 
have a playground and every mother a 
breathing spot within easy walking dis- 
tance of their homes, points out 15 in- 
stances of “special park opportunities” 
in the final section of his report on city 
planning, made to the Pittsburgh, Pa., 
Civic Commission. 
The plans for the improvement of 
Balboa Park, San Diego, Calif., pre- 
sented by Olmsted Bros., Boston, were 
accepted by the park commission.
