The Cottony Scale. — Pulvinaria Innomerabilis. 
Charlotte, Vt., July 2, 1900. 
Editor Park and Cemetery. 
Dear Sir: — I am just home from the west and while in 
Chicago and one or two other places near that city I noticed 
what I took to be a scale on the underside of the branches of the 
Silver Maples. It was abundant in Humboldt and Garfield 
parks and out at LaGrange I found it much more so. I found 
a trace of it up at Racine, though only a trace. I dare say this 
is well known to those who are familiar with such things, but 
as I never had seen it before I wondered if it was confined to 
that particular location. I could not find it on any other tree 
than the Acer dasycarpum. I looked for it up at Rdgerton and 
Milton Junction, Wis., but did not see it there. I am anxious 
to know what it is and how far it has spread. 
Yours truly, F. H. horsford. 
Chicago, Illinois. 
Pulvinaria innumerabilis is present everywhere in this part 
of the state. I have seen it from Waukegan to Elgin and all 
around Chicago. This scale insect is found usually on the soft 
maple, acer dasycarpum, and its varieties, and is therefrom also 
called the “cottony maple scale,” but it is just as plentiful on 
some of the Crataegus species, especially on C. tomentosa and 
coccinea; it also infests the ash-leaved maple, acer negundo, 
and 1 have seen it on the honey locust, gleditchia triacanthus 
and G. enermis. This louse first settles on the leaves and later 
migrates to the twigs where it is easily noticed by the waxy or 
cottony egg mass. The proper time to fight it is at its early 
stage, June, and can be done by spraying with kerosene emul- 
sion. Its natural enemy is a beetle belonging to the lady-bug 
section and is found at work in the egg mass quite frequently.

Milwaukee, Wis. 
The Cottony Maple scale, pulvinaria innumerabilis, made 
its appearance in Milwaukee two years ago and did consider- 
able damage last summer, in many cases causing the death of 
the tree attacked. This summer it does not seem to be so bad. 
Its attacks as far as I have obs,.rved are confined to the soft or 
silver maple. Remedy, spraying with kerosene emulsion. 
Efforts should be made to stamp it out. J. Currie. 
Kansas City, Mo. 
We have had no trouble this year from the maple bark 
louse or cottony scale but had considerable last year. Our 
great pest this year is the green-striped maj^le worm, anisota 
rubicunda. Many large maples are entirely stripped of leaves 
and parts of our grounds look like the fall of the year.

The scale is a very large one about % inch across. We find 
a few scattered specimens on all our silver maples. It is not 
abundant but is well distributed as nearly every tree has a few. 
A somewhat superficial search has failed to locate it on the 
Norways or any other tree. IV. N. Rudd.

Azaleas. 
Philadelphia, Pa., July 27, 1900 
Editor Park and Cemetery. 
Dear Sir: — It was a surprise to me to read in Mr. Jensen’s 
notes on az ileas that the Ghent varieties ‘ ‘are rarely seen in 
parks and gardens. One reason for this is, of course, their 
tenderness, which at present precludes their adaptability to the 
northern parts of the middle states. T Isn’t this a little mis- 
leading? The general impression is- that Ghent azaleas are 
anything but tender. My own observations are that they stand 
10“’ to 15° below zero without any injury whatever. Although 
there are doubtless exposed situations where they would not 
thrive, nursery firms in Pennsylvania have sent them to custom- 
ers in all parts of the country for many year.s, with no complaint 
of their lack of hardiness. J. M .

Planting Single Graves. 
New York, July 30, 1900. 
Editor Park and Cemetery. 
Dear Sir: — I think Mr. Rudd is crowding me a little 
unkindly when he limits my planting of perennials, annuals 
and bushes to “a grave space one and one-half by four feet.” 
This is surely gardening or landscape gardening o.i an uncom- 
fortably small scale, and extreme cases like this are hardly fair 
tests of the value of general suggestions such as I made in my 
article. 
The true solution of the problem of planting very small 
cemetery lots is probably to include a number of them in one 
scheme of treatment. If they must be treated separately, they 
may be planted even with bedding plants without arranging 
them into stars or anchors or floorcloth patterns. As for the 
“white or delicate pink geranium” that is merely a matter of 
taste. If Mr. Rudd, after looking with cleared ejes on the 
annuals and perennials, prefers his geranium, I cannot dispute 
his right to do so. For my part, I would prefer most of the 
annuals and perennials that do not grow too tall and last a 
reasonably long time in bloom. If I am asked to name any 
particular one, the first that occurs to me is dwarf nasturtiums.

NOTES. 
Plans have been filed with the commissioner of the depart- 
ment of buildings. Borough of Queens, Brookl3n, N. Y., for a 
crematory in Long Island cit3G The building is to be 40x49 
feet with an incineration chamber 25x16 feet, and it will cost 
$20,000. 
^ - 3 ^ 
Competitive plans for the aqu rium building to be built by 
the board of park commissioners of Detroit, Mich., will be 
received by that b dy unAl October 45, and the jury of archi- 
tects to award the prize will have until Octob r 25 for their 
decision. With all this it is not expected that actual work will 
begin before next spring.

Mr. A. H. Allen, of Red Wing. Minn , who has given the 
subject of country cemeteries much attention, says in the local 
newspaper: “The first great need of the country cemetery is 
organization of citizens for the purpose of improvement. The 
next is the adoption of a predetermined effort to improve. 
The advantages accruing from these successive steps are loo 
self-evident to need explanation. The clearing out of weeds 
and objectionable accumulations, of vegetable debris, the mend- 
ing of roads and paths, the mowing of grass where it is w’orth 
saving and the sowing of it to lawn surface, are among the first 
steps to renovate the country burial ground. Then might fol- 
low the planting of shade and memorial trees, the filling in of 
exposed and vacant places with appropriate shrubs and the 
planting of vines and trailers to embellish the boundary fences. 
With the improvements carried so far it n ight be a good time 
to formulate and adopt rules looking to the preservation of 
what had been done as well as the eontkiued care of the 
grounds by the lot owners and all interested.’"’
