tliis is accomplished by what is 
termed “solid stream” spraying, which 
is to force from a straight bore noz- 
zle, varying in size according to the 
height of the trees to be sprayed, a 
stream with sufficient force to thor- 
oughly break it into a mist after the 
height is attained. 
It has been found for general wood- 
land spraying, where the length of 
hose used varies from 1,000 ft. to 
1,500 ft., 300 pounds or more pump 
pressure is necessary and, in extreme 
cases when the spraying operations 
are on considerable height above the 
sprayer, even 350 pounds is used 
One of our pictures shows a 
sprayer at work on the U. S. Capitol 
grounds at Washington, D. C., for 
the suppression of Elm-leaf beetle 
and Tussock moth. Notice the dif- 
ference in height attained by a 14- 
in. and a %-in. open tip, operating 
on a Worthley nozzle at the same 
initial pressure, the J4-in. tip being 
inserted during the spraying of trees 
not exceeding 40 ft. in height, or for 
reaching the lower limbs of large 
trees. 
This size was originally designed 
for heavy woodland work but, since 
its introduction, has become a favor- 
ite for municipal and park work. It 
delivers 33 gallons per minute at 350 
lb. pressure. It consists of a “U” 
shaped pine tank of 400 gal. capacity 
with a detachable cab, covered on top 
with best oiled duck to protect the 
machinery, which is mounted on a 
platform, cut-under, two-horse spring 
gear with compound brakes and five- 
inch wheels. 
The pump is operated by a four- 
cylinder, 10-14-horsepower gasoline 
engine with Bosch magneto and me- 
chanical oiler. The engine is cooled 
by a coil submerged in the solution 
tank and is connected to a supply 
tank fitted with a glass water gauge. heavy galvanized Non, holding suffi- 
The gasoline tank is made of extra cient fuel for a two-days run.

STATION GROUNDS THAT SERVE AS CITY PARKS 
The growth of railway station gar- 
dening in recent years has made re- 
markable progress, and there has been 
fine work done in the development of 
the station grounds. Seldom, however, 
does the railroad station park become 
such an important part of the city park 
system, as will be the case in stations 
now being developed by the Canadian 
Pacific about its stations at Red Deer 
and Macleod, Alberta. Plans have been 
prepared for the development of these 
grounds by Richard Iwerson, superin- 
tendent of parks at Calgary, Alberta, 
and the grounds as may be seen by the 
illustrations of the plans herewith em- 
body elaborate ornamental and service 
features that make them integral and 
important parts of their respective city 
park systems. 
Both these station grounds, being sit- 
uated on the edge of the towns and fac- 
ing them, will strongly affect the peo- 
ple of the towns as well as the travel- 
ing public. 
On the Mcleod plan, the park, which 
covers a whole block, is the property of 
the railway, but the town has a lease 
on it and has to provide the funds for 
the laying out and upkeep. On one 
end of the grounds may be seen a space, 
which will be equipped with a com- 
plete set of modern playing apparatus. 
The big flower bed arrangement in 
the center of the grounds will have an 
cpen massive hall in Doric style, which 
will also serve as a band stand. This 
band stand will be placed on top of a 
little hill about 15 feet high. 
The sunken garden near the station 
platform, which will have two foun- 
tains, will be laid out at the expense of
