hold of the fresh soil, after which a liberal supply will be necessary, 
and the syringe should be used morning and evening to keep the 
foliage in a clean healthy state. The plants had better not be sub- 
jected to a higher night temperature than from 50° to 55°, and 
they should be removed to a cold frame as soon as the weather will 
admit. If the frame is placed so as to be screened from the midday 
sun, the plants will be less liable to the attacks of red spider, and 
unle.'S such is the case, a thin shade should be thrown over the glat-s 
on the forenoons of bright days. This Ind'gofera is a vigorous 
grower, and healthy plants will require a second shift; they will 
probably be ready for this early in June, and it should not be 
deferred after it is wanted, otherwise the growth of the plants will 
be checked, and it is desirable to have the pots well filled with roots 
before winter. Very little attention will be required in training the 
specimens in any desired form. The branches should be held up at 
regular distances apart, so as to admit light and air, and any shoot 
which inclines to take a decided lead must be stopped, so as to 
maintain a compact and regular form of growth. After about the 
middle of August the object should be to ripen the wood, and to- 
effect this it w ill be necessary to expose them freely to sun and air, 
and to lessen the supply of w ater at the root. When damp weather 
occurs, unless the wood is well matured, remove the plants to the 
front of the greenhouse, or to any airy position, w here the ripening 
of the shoots will be completed. Plants the growth of which is 
properly matured will winter safely anywhere out of the reach of 
frost, and a few degrees of this will not injure them, but improperly 
ripened wood is apt to damp off, therefore it is worth while being afc 
some trouble to get the young shoots thoroughly matured previous 
to the damp, foggy days of November. Water should be altogether 
withheld while the plants are in a dormant state. In cases where it 
is desired to obtain large spei-imens without loss of time, the plants 
may be placed in growing circumstances early in spring, taking care 
to bring the soil into a moist, healthy state, and to keep the foliage 
clean and healthy. 
By attention to potting, etc., during the season, as recommended 
in our last, large specimens w T ill be obtained previous to winter. 
The treatment under which I have found full-grown specimens to 
flower most profusely, and continue the longest in perfection, is to 
keep them dry at the root during winter and till late in spring, and 
thoroughly moisten the soil, letting the plants occupy a place in the 
closest part o the greenhouse, and moistening them overhead fre- 
quently, until they commence flowering, which may be about June 
or early in July, according to the time at which they are started into 
growth. By giving a liberal supply of manure-water during the 
period the plants are in bloom, and keeping them in a close part of 
the flower-house, they will go on growing and flowering in great 
perfection for some two or three months in succession, and few 
plants ate more handsome than large well-bloomed specimens of this 
Indigofera. A moderate shift should be afforded the specimens 
annually as long as this can be conveniently dons; and when the 
size of the pots renders this impracticable, the balls may be reduced.
