should vary according to the weather and the growth. It is 
important, however, to water in the morning, for if the 
foliage is wet when the sun is powerful, brown blotches occur 
where the drops of moisture have rested. To produce fine 
bushy plants early flower buds should be panes off so that 
the strength will go to the plant itself, and the leading shoots 
should be removed to encourage side growths from lower 
down the stem. In order to bring forth showy specimens 
growth should be stimulated by feeding with liquid manure 
_ two or three times a week. The liquid manure may be made 
by suspending a half-bushel sack of cow manure in a 50- 
gallon barrel of water. 
In October, when signs of ripening begin to show, the 
water should be gradually withheld until the growths decay, 
and the pots then placed on their sides under the benches 
in a greenhouse at a temperature of 40°F.; or the tubers 
ma taken out of the pots and placed in dry sand in a 
cool cellar. In either case, care must be taken to prevent 
any moisture from reaching the tubers raat 2 the restin 
period. In the spring, as soon as the tubers show signs 0 
wth, they should Gs potted, the best plants being pro- 
uced during the second year, although they are good for 
several years. 
Propagation.—Tuberous begonias are propagated by seeds, 
division of tubers, or by cuttings of side shoots, the most 
common and satisfactory method being from seed. The seed 
should be sowed in sallow boxes or seed pans about Febru- 
ary 1, the compost consisting of equal of leaf mold 
and peat and one-quarter ¢ a e seed are very 
minute, resembling tobacco dust, and for this reason are 
best sown directly on the surface of the soil. The pan 
should be covered with a glass pane and shaded to prevent 
drying out, but as soon as the mg es the glass and 
the shading should be removed. en the plants show the 
third leaf they should be pricked into flats containing a 
compost similar to the one mentioned above, and spe 
two inches each way. It is advisable to keep the flats in a 
moist atmosphere, and near the glass of the nhouses to 
prevent spindling. Later the plants should be transferred 
to four-inch pots using soil similar to that used for the 
po aes The subsequent treatment corresponds to that of the 
If it is desired to retain and increase the stock of any 
variety this may be done by taking cuttings of side shoots, 
two to three inches long, during the summer and inserting 
them into leaf mold, sphagnum moss, or cocoanut fibre. The 
cuttings should be kept close and shaded for several days, a
