suniincr, they succeed quite as well, if }duuged amongst other 
alpines, and treated according to the general directions given 
under the 58th section of this Auctarium. During winter, a few 
plants may be placed in the cold frame.

ted in April, just before they commence growing; which is also 
the season for dividing them. The best soil is pure peat, with 
one third part sand. Pots of small size to be used, and these 
to be nearly half filled with drainers. As the plants increase 
in size they should be removed into larger pots; taking care to 
keep the balls entire about their roots. Parnassia Carolina, re- 
quires the protection of the cold frame in winter. 
71 Potatoes, culture of. In the Irish Farmer’s and Garden- 
er’s JMagazine, several communications have appeared on the 
culture of the potatoe. As this is a subject of no mean importance, 
to English as well as Irish, we shall give a few general ideas 
from amongst the conflicting opinions delivered in that work, 
and by cultivators of our own acquaintance. Several writers 
agree that potatoes which have not been well ripened, and fully 
matured in autumn, are unfit for planting. This may be cor- 
rect iu reference to a general crop, but we know the practice of 
some experienced men, is to plant for a late crop, on the ground, 
which has been cleared of early pease; to obtain somewhat im- 
mature potatoes, expressly for the supply of the next year’s sets, 
of the earliest sorts. These, certainly, produce an earlier crop; 
but as early produce is by no means synonymous with large 
produce — the desideratum of a main crop, it may be as correct 
as it is reasonable, that well-matured potatoes, are the most suit- 
able for the purpose of reproduction. The next point of con- 
sideration is, their preservation, during winter. It is pretty gen- 
erally agreed, that permitting potatoes to be exposed, and be- 
come dry, deteriorates their quality for the purpose of planting. 
Another very important difterence exists in the practice of atten- 
tive potatoe growers, regarding which it may be unnecessary to 
give details of experiments; inasmuch as most persons know 
that large potatoes, when planted whole, produce a better crop 
than when cut into sets; and that large potatoes, for this purpose, 
surpass small ones. This, however, as a general practice, is re- 
jected by most growers, on the ground that planting whole pota- 
toes is the most expensive. It must be admitted as somewhat
