and it would depend somewhat upon 
the decision on other points. My judg- 
ment at present is that the area north 
of the Formal Garden would be the most 
convenient and suitable. Little children 
usually come with parents and they 
would naturally be interested in walking 
through the Formal Garden and going 
later over the Zoological Gardens and, 
perhaps, to the Picnic Grounds. There- 
fore, a Playground located as suggest- 
ed would be easily reached. At the 
same time, the general area mentioned is 
sufficiently large to permit of heavy 
planting as a screen between the Form- 
al Garden and the Children’s Play- 
ground. 
(9) The Picnic Grounds: In all 
probability, there ought to be at least 
two picnic grounds, one at the west 
end and one at the east end. The ap- 
proximate location of these has been 
indicated on the plan. They should 
have suitable planting and in the case 
of these grounds, I think a good lawn 
should be established and maintained. 
Of course, they should have tree shade 
and be furnished with drinking-water, 
FIGHTING FALL 
Editor Park and Cemetery ; 
I would like to tell you of an experi- 
ence we have had during the years of 
1910 and 1911 in fighting the Fall 
Canker Worm Anisopieryx Pometaria 
and express some conclusions I 
have come to, as to the use of poi- 
son in fighting these insect pests, 
which rarely kills the insect but often 
kills the blessed bird, the best guar- 
dian that stands between vegetable 
growth and the myriads of pests that 
prey upon it. 
During May in 1910, I noticed many 
Canker Worms in a section of Beards- 
ley Park wh^re we were having some 
work done. They were abundant on 
nearly all kinds of shrubs and trees, 
denuding many of the Wild Cherries, 
Red Maples, Black Ash, Iron Wood, 
etc., of nearly all their foliage. On 
becoming full grown, we noted that 
they came down by their web and 
went into the ground. They reap- 
peared in another form on the 21st 
of November. The females as wing- 
less moths, preceding the males a 
little who were supplied with wings. 
The females crawl up a tree (or any- 
thing else) making 3 to 5 feet a day, 
resting in exposed places to be fer- 
tilized by the males who fly to her, 
after which she crawls at a faster 
gait up the tree to deposit her eggs. 
tables, and other picnic conveniences. 
(To) Japanese Garden: A Japanese 
Tea Garden, such as one usually finds 
in parks in Californian cities, would be 
a feature of attraction. A suitable lo- 
cation could easily be decided upon. It 
seems to me it ought to be in the west- 
ern end of the park, not too far from 
the Lake, the Formal Garden, and the 
Zoo. These popular features should 
be placed in convenient relation. 
(11) The Boivling Green: The 
Bowling Green is a minor feature and 
yet it is beautiful in itself and an ap- 
propriate form of sport for inclusion in 
the park. I am not yet certain whether 
this had better be placed in the Tennis 
Grounds or nearer the Children’s Play- 
ground and Formal Garden. It could 
readily be provided in either place. 
(12) The System of Drives and 
Walks : In so large a park as Del Paso, 
the system providing circulation for 
vehicles and people is of greater impor- 
tance, probably, than any other single 
thing. The provision outlined on the 
plan seems to me ample, although, of 
course, it could be extended. The plan 
By Charles E. Keith, Superinten- 
dent of Parks, Bridgeport, Conn. 
It occurred to us that as they came 
onto the tree would be the best time 
to kill them. We selected a group 
of 25 trees of various kinds and sizes 
and killed all Imagos as long as they 
came up, which ceased Dec. 23. 
During May of 1911 our group of 
trees were nearly free of worms, so 
much so, that we decided to continue 
the battle another season throughout 
the whole park, consisting of some 
200 acres, containing some 10,000 nat- 
ural indigenous and foreign trees. 
The moths made their first appear- 
ance this year (1911) on Nov. 11. 
Selecting a Red Maple 14 inches in 
diameter I watched for and killed on 
each day all Imagos that came to it, 
not finding any after Dec. 20, and 
only stragglers after Nov. 29, making 
a total for my trees of 1,722 females 
and 34 males. There were killed on 
this park between the dates just men- 
tioned aside from my tree 210,000 Ima- 
gos at an expense of $80.00. 
I take the liberty to quote from 
Prof. C. V. Riley’s report of 1880 
and 1882 where he stales, that a num- 
ber of impregnated female Canker 
Worms raised in confinement, laid an 
average of 240 eggs each. This num- 
ber multiplied by 210,000, gives an 
excess of 50,000,000 possible worms 
that were destroyed at a cost of 
lirovides 15 miles of dri\cs, 29 miles of 
walks, and about 12 miles of bridle 
paths. The princii)al drives and walks 
are those which run in general parallel 
to the Creek and the lake shores. There 
are good boundary roads also. Walks 
would be carried through the Wood- 
land, especially to the more interesting 
elevated points affording outlooks. The 
widening which I have recommended 
for the Auburn Boulevard and for the 
Wheatland Road would, I believe, prove 
advantageous. As those roads are laid 
out at present, they would not be ade- 
quate to take care of the additional de- 
mands that will probably be made upon 
them in the future. A liberal provision 
for circulation around and through the 
park, as provided in the Preliminary 
Plan, is something which I should rec- 
ommend the Committee to consider care- 
fully. Here again, however, there would 
be no necessity to execute all of the 
recommended roads at once. Without 
disadvantage they could be taken up in 
some systematic way, constructing the 
most urgent at first and postponing the 
others until needed. 
$80.00; and no harm done to the tree 
or the good cannibal and parasitic 
flies, insects or birds. Prof. Riley 
speaks of a parasite fly, the Micro- 
gaster and the Tachina, which de- 
stroys these worms in large quanti- 
ties. He also speaks of a very min- 
ute specie of Platygaster which de- 
stroys the eggs, also the Nothrus that 
eats them. The Spotted Lady Bird 
which eats the young and the Fra- 
ternal Potter Wasp who stores large 
numbers of these worms in her cells 
as food for her young, nearly all of 
our birds are fond of, and eat im- 
mense quantities of these worms. The 
report also gives a list of 45 specie 
of Birds in Connecticut and Massa- 
chusetts that feed on the Canker 
Worm. 
In years gone by much money has 
been spent to banish this worm. Many 
sticky substances have been used, 
numerous devices patented and un- 
patented were tried, traps of all kinds, 
and some quite expensive, were used. 
The boring of holes in their trees 
and plugging sulphur therein was 
practiced in many parts of the coun- 
try and never killed a worm. Many 
farmers becoming so discouraged in 
fighting this pest cut down their or- 
chards and burned them on the ad-
