containing one or more eyes, is the general plan for 
obtaining a crop. A good, friable, well-drained loam is 
considered best suited for their culture. Selecting for 
the purpose an early variety such as Improved Ash-leaf 
Kidney, the first outdoor crop should be planted not 
later than the middle of March on a warm, sheltered 
south border. The end of March or early in April is a 
good time to plant the main crop. 
PoTENTILLA.—The hardy herbaceous perennial kinds 
are propagated by division in autumn and spring, and 
by seed sown about the middle of March. 
PrimuLta.—There are now several different forms of 
P. sinensis, of which P. stellata is very popular owing 
to its free habit and profuse flowering propensity. The 
seed should be fresh and sown in well-drained pans filled 
with a mixture of two parts loam, two parts leaf-mould, 
and one part silver sand, sifted through a 4-inch sieve, 
pressed down lightly and level, watered, and allowed to 
drain. It is then ready for sowing the seed thinly and 
evenly over the surface, to be covered with a very thin 
layer of the fine compost, placed in a warm frame, and 
covered with a pane of glass until the seedlings appear. 
When big enough to handle, prick off in pans of similar 
compost, keep close and shaded for a few days; in due 
course transfer singly into small pots and grow on ina 
cold frame, the pots standing on a bed of coal ashes. 
The double varieties are considered difficult to propa- 
gate and to cultivate, but we have known men who grew 
them, as expressed by the old saying, ‘‘ like weeds.” 
They are propagated by cuttings taken off the base of 
old plants with a heel, planted singly in small pots, 
surrounding the base of each cutting with pure silver 
sand, the leaves tied to a stick to keep all steady,
