contention and quell disorder and quiet boisterous- 
ness that tire and destroy instead of refresh and cre- 
ate. It is the place for the gladness of the people. 
Gladness is a broad factor in the morality of the 
people. When people are glad, anarchy does not 
liatch its evil brood and the destroyer of life has no 
place. 
A sullen people is a dangerous people. A glad 
people is a moral community. Not everything ol 
morality is in gladness. But the color of morality is 
gladness.”

The Saururus, Piper, and Monimia Alliance. 
For the most part this too is a tropical and sub- 
troj^ical group of 6 tribes, 39 genera, and 1,299 spe- 
cies. It includes trees, shrubs, climbers and herbs, 
some of which are aquatics. These latter offer the 
only representation of the group for cold temperate 
regions. 
In south Florida and southern California the rep- 
resentation may be made more full. Many of the 
peppers require shade and moisture to grow them 
well, but it is possible a few sub-tropical trees of 
the group hitherto overlooked may be grown to 
afford it. 
Saururus has two species, S. Soueri from Eastern 
Asia, and S. Cernuus, a pretty white flowered aquatic 
known as thq^'dizard’s tail,” is common from Ontario 
and Minnesota southward. Its flowering season is 
only about three weeks, but it is a particularly good 
looking plant, keeping a cheerful green until frost, 
not disposed to spread unduly, and although about 
the only representative of the group possible in 
northern gardens, hardly ever seen in cultivation. 
It may easily be collected and grown in a shallow 
pond or on the margin of a slow stream where the 
soil is muddy and rich. The Saururus has cordate 
leaves and terminal spikes, but the illustration of a 
Piper gives an idea of the aspect. 
Houttuynia is a similar aquatic genus in two or 
three species. The Japanese H. Cordata is in Euro- 
pean gardens. H. Californica, found from northern 
California to the Rio Grande, is rare in cultivation. 
It has a short conical spadix, with small white in- 
volucral leaves. 
Piper is the black pepper genus. There are 650 
species, including the long pepper, the betel pepper- 
and others. The species are widely distributed and 
are mostly shrubs, climbers and herbs. They are 
tropical or sub-tropical. To read their characters is 
monotonous, but the various sections afford several 
handsome plants. P. Euto-Kadsura will probably 
be hardy along the Gulf of Mexico and in Florida, 
as it is in the south of England. It is said to bear 
red fruits. Some of the tropical economic kinds are 
said to endure in the shade in south Elorida, and 
such as P. porphyrophyllum, P. metallicum, P. de- 
currens, P. excelsum vars., P. Tomentosum, P. rubro- 
venosum and also such climbing kinds as have 
showy fruit should be tried as ornamental plants. 
There are a number of fine climbers at considerable 
elevations in the tropics, not yet in cultivation. 
Peperomia is a genus of ornamental leaved herbs, 
so far. as the garden kinds are concerned. There

are 400 species known to science, found in the same 
regions as the peppers. 
Chloranthus, in ten species, are mostly tender 
shrubs. C. trachystachys, from China and Japan, 
seems to be growing in the Kew arboretum. 
Myristica is the “nutmeg” genus in ninety species 
of tropical trees and shrubs. 
The genera Peumus, “Boldea,” Atherosperena, 
Doryphora, Saurelia, and Daphnandra, are mostly 
monotypic, handsome trees from Ghile, Australia and 
New Zealand. James MaePherson. 
AN INSECTICIDE FOR ROSES. 
E. E. Rexford, in “Gardening,” recommends an 
inexpensive insecticide for roses. He says, take a 
half pound of ivory soap, shave finely, and add to two 
pailsfull of water. Heat it until dissolved, and apply 
with an ordinary garden sprayer, taking great care to 
reach every part of the bush. Begin early in the sea- 
son and go over the bushes twice a week, until the 
time for insects is past.
