in diameter. The first transplanting begins immediately after 
the cotyledons have opened. If the plants are left in the beds 
too long, it is very difficult to transplant them without giving 
any injury to the roots and cotyledons. As a matter of fact, 
it is very much desired by growers to keep the cotyledons on 
the plants until the flowering season; therefore, the growers 
should take much pains to keep them as long as possible. 
‘‘Fertilizers: Rape cake is generally used as a fertilizer, 
which is frequently applied to the soil in the form of powder, 
but mostly in liquid, which is thoroughly fermented. Chili 
saltpeter, ammonium sulphate, or potassium sulphate, ete., is 
frequently used as a substitute of the first named. 
‘‘Watering: The seed-beds should be always moistened 
until the young plants appear on the ground. After trans- 
planting it is a usual practice to water twice a day, one in the 
morning and the other in the day time. It is desirable to 
use warm water for the day-time watering. 
‘‘Supports: When the plants grow up to 6 or 7 inches 
high, it is absolutely necessary to furnish some supports. For 
this purpose bamboos or reeds are generally used. The sup- 
ports are arranged in various ways, of which the following 
two are very common: 
‘A, ‘Andon’ type (Lantern type). 
‘*B, ‘Boshi’ type (Hat type). 
‘A. Andon type. Height of the supports is dependent 
upon the individual tastes. Erect four or five bamboos or 
reeds along the inside of the pots, and connect them with 
three rings of bamboo. 
‘*B. Boshi type. <A piece of bamboo is bended down to 
the soil, thus making an arch-like form, which is then crossed 
with two pieces of bamboo. This type of support is especially 
recommended for some special varieties which have hard 
stems. 
‘*For the morning-glory culture it is a matter of most im- 
portance to help the stem of the plants to climb up the sup- 
ports. The most desirable time for winding the stem is during 
day-time, as it is very tender, while in the morning or evening 
it is very brittle and could not be wound without causing any 
injury to the plants. The stems naturally twine the supports 
from left to right, therefore it should be arranged in that 
way, otherwise the stem may refuse to twine the supports.
