ON A MODE OF PROPAGATING THE CALA'MPELUS, (SCA'BER) 
OR, kcremoca'rpus (sca'ber.) 
In the montli of January, place an old plant in a vinery or hot-bed 
so as to get it to break ; when the shoots are about three inches long 
take them off with a sharp knife, being careful to take a small 
piece of the old bark with the cuttings, and plant them in hght 
vegetable mould and sand under glasses ; they will quickly strike 
root, and in a month will be fit for potting ; the composition should 
consist of equal parts of rotten dung, leaf mould, and loam. Plants 
raised this way from cuttings will flower well the first year, when 
those raised from seed will not blossom till the second year. In 
raising from seed, it should be sown as soon as ripe, and placed in 
the green-house ; the plants will be fit for potting in the spring.

SOME SUGGESTIONS RELATIVE TO THE CULTIVATION OF 
DIFFERENT SPECIES OF ROSES.— Br I. T. 
In the many excellent observations, on the cultivation of the rose, 
which have appeared in your Register and other works on horticul- 
ture, I have frequently observed that the rules, though most excel- 
lent in themselves, as applied to many species of roses, have usually 
been too general, and have proceeded on the principle of considering 
most species as requiring the same modes of treatment, while the 
great difference in the habits, nature, places and manner of growth 
seem to me to point out imj)ortant variations in the soil, situation, 
and mode of cultivation required by many of the different species. 
I therefore would state some of the differences and places of growth, 
in a wild state, of some of the species, and the variations that they 
seem to suggest in the culture. Though plants are greatly altered 
by culture, yet they generally retain a considerable bias to the soil 
and situation for which, by nature, they are formed ; and it is 
usually within a certain range only, of what I would call, their 
natural habits, that they are capable of improvement by cultivation. 
In taking a cursory view of the difference, which there appears 
to me, to be among some of the species of roses, I shall, to make 
myself better understood, separate the genus into five divisions.
