looking ones will require 2 or 3 years more food before 
they are capable of throwing blossom. Fine rich soil 
should be worked in between the crowns when plant- 
ing, and about 2 inches of soil should coyer the tops 
when finished. Each autumn a good layer of well- 
decayed manure should be spread over the plants, so as 
to supply fresh food, and secure fine blooms. Treated 
thus the plants may be left undisturbed for several 
years in the same place, nntil they become too crowded.

produces its lovely funnel-shaped blossoms from July

to variety. The plants are useful in beds and borders, 
and are easily raised by seeds sown in heat about

is often a troublesome weed, but if properly used to 
cover trellises, rocks, &c., with its trailing stems, it 
looks handsome when bearing its white, pink, or pale- 
purple blossoms. (See Calystegia and Ipomxa.) 
COREOPSIS (or Calliopsis). — This genus consists 
of pretty annual, biennial, and perennial species. The 
annuals, of which the yellow-flowered C. Drummondi 
is the best known, are easily raised from seeds sown in 
gentle heat in March, the young plants being ready 
for planting out by the end of May. G. aristosa, G. 
atlcinsoniana, and coronata, are other yellow-flowered 
kinds, the two latter having a reddish-purple blotch at 
the base of each ray floret. Another charming annual 
is G. tinctoria, whose finely-cut leaves and yellow 
flowers with a purple-brown blotch at the base of the
