A Pleasing Sample of French Landscape Gardening 
An interesting })osl-ear(l was received from one of our 
boys in France, the name of the owner of the residence 
and locality were censored, which we considered well 
worth reproduction in the National Nurseryman, mainly 
on account of the landscai)e treatment around the resi¬ 
dence. 
The landscape treatment is quite a contrast to the style 
practiced in this country. It will he noticed that every 
front are evidently the Bay trees in scpiare boxes. 
The plant in the cenhu- of the lawn has the outline and 
habit of a box hush. The tall columnar tree to the left of 
the picture is possibly a very fine specimen of the Irish 
Yew or else one of the Arhon itaes, the latter most likidy. 
The large tree between it and the house has th(‘ outline 
of the Red Maple or one of the Oaks. The three conifers 
appearing above the roof of the house are (widently var- 
/I postcard from one of our boys in France, showing a pleasing sample of French Landscape Gardening. 
tree and plant is an individual specimen, and yet a pleas¬ 
ing combination is obtained as a whole. 
The individual outlines of the trees show to their full 
advantage, and give varying contrast with each other. 
They are arranged rather to frame the house than to hide 
it, as is so often done in this country. 
It is practically impossible to identify for certain the 
various plants seen, hut the round headed trees across the 
ieties of Abies or Picea, while the portion of the tree ap¬ 
pearing on the right side of the picture, suggests the 
Beech. 
The fence along the front suggests the neatly trained 
English Ivy. Although the list of plants used is com¬ 
paratively small, most will agree that the effect is ex¬ 
tremely pleasing and much to be preferred to the massed 
plantings commonly seen in this countiy. 
A NEW CONTACT INSECTICIDE 
Under Scientific Notes in the Journal of Economic En¬ 
tomology, William Moore gives an account of a promising 
new Contact Insecticide. From the results of a series of 
experiments, it has been determined that the most efficient 
contact insecticides must he of an oily or soapy nature. 
Based upon these obseiTations, a new contact insecticide 
has been made by the formation of a soap or soap-like 
salt by the union of nicotine and oleic acid. This chem¬ 
ical is nicotine oleate. It dissolves in soft water forming 
a soapy solution which may he used to emulsify an 
animal, vegetable or mineral oil. 
The following experiments give an idea of its value. 
First, Nicofume, containing 40 per cent of nicotine di¬ 
luted with water to give a nicotine content of 1 part in 
1,000 of water, killed 95 per cent of the chrysanthemum 
aphis. Nicotine oleate, diluted to give 1 part of nicotine 
in 1,500 parts of water, killed 96 jier cent, while diluted 
to 1 part of nicotine in 4,500 })arts of water killed 65 
per cent. 
Second, Nicofume, diluted to a nicotine content of 1 
part in 1,500 with 2 parts of laundry soap added, killed 
93 per cent of the chrysanthemum aphis, while the nico¬ 
tine oleate with a nicotine content of 1 to 2,250 killed 97 
per c(mt. 
Third, Nicofume in a(|ueous solution does not kill 
mealy-bugs. Nicotine oleate used at the rate of 1 to 50t) 
will kill a few mealy-bugs and a few egg clusters. Two 
per cent of a vegetable, animal or mineral oil emulsified 
in the nicotinei oleat(^ solution will kill nu'aly-hugs and 
their eggs. An emulsion containing 1 i)arl of nicotiin* in 
500 parts of water with 2 per cent kerosene killed 79 p(‘r 
cent of the adult mealy-bugs and their older larva‘, 98 
per cent of the eggs, and 98 per cent of the young lar^aj. 
Fourth, Preliminary experiments have shown that
