flecks of sawdust. Use carbon bi-sulpkicle. As an added 
curative the amateur inserts a wire into the hole, persistently 
pushing until she knows that something has happened at the 
inner end. Then the carbon bi-sulphide on cotton, is quickly 
applied and the hole sealed with wax. For oyster-bark scale use 
black leaf 10 according to formula. 
The Lilac is easy to cultivate, endures abuse, has few enemies. 
It demands a cool enough climate in which -to rest and ripen 
its wood. Sudden changes are disastrous to Lilacs ; the buds 
swell quickly, the frost nips them, the flowers are gone. 
In Rochester during May, we watch the thermometer 
anxiously. Our conversation is weather-weighted. Is it a good 
season for Lilacs? Are they too far advanced? If the storm 
signals indicate frost while the flowers are expanding we all 
bestir ourselves. The Peaches may be frozen, the Cherries 
ruined, but the Lilacs — never! We fly for the muslin garden- 
protectors. AYe commandeer coverings of various hues. If the 
danger is great and our collection large, we rifle the linen closet. 
Next morning, even handsome gardens, look like sections of Little 
Italy on wash-day. But we save the blossoms. 
Autumn is the best time for planting Lilacs. Growth starts 
early. If spring work is delayed the plants will be in an 
advanced stage and vegetation thereby checked. This is the 
advice of the Park's noted horticulturist, John Dunbar, under 
Avhose care twelve named (and several numbered) varieties have 
been added to the Highland collection. President Lincoln is a 
beautiful single blue; Adelaide Dunbar, semi-double, maroon to 
violet-red; A. B. Lamberton, semi-double, violet-heliotrope; W. 
C. Barry, single, lilac-pearl; General Sherman, single, pearl- 
lavender. A list of a few of the Park's best single and double 
varieties will be found at the end of this article. Unless one 
wishes to make a separate collection, Lilacs should form a part 
of the garden's color scheme. The double varieties are best to 
use for formal planting because smaller in size and more uniform 
in growth. Single varieties look best planted with single, double 
with double. A promiscuous blending of colors is ruinous to an 
artistic effect. 
An ideal planting of Lilacs is in front of a hedge or 
shrubbery, running east and west, and if possible, on the south 
side of the garden. In this position the slanting rays of the 
sun fall on the flowers during the morning and afternoon 
while during the middle of the day the light comes through the 
blossoms, producing an entirely different effect. The bushes 
also cast half-shadows on your fore-ground planting. To leave 
this space bare is wicked waste of rare opportunity. The habit 
of the Lilac is to blossom at the end of its branches growing 
from the middle and top of the shrub. The Lilac's colors, there- 
fore, should be brought down, tied to earth, by judicious plant -
