DREER’S VEGETABLES UNDER GLASS. 59 
Red and white varieties of radish (preferably the turnip- 
rooted sorts) are used for under-glass culture. Of the reds 
we know of nothing at this time superior to Cardinal Globe 
and White-Tipped Scarlet Gem, although a new radish of 
merit, almost leafless, has just (1896) been sent to America 
from beyond the sea. It must be tested here before it can 
be endorsed. White Box, of many shades of variety, is a 
favorite everywhere, both under glass and in the open 
garden. 
In heated structures radish seed may be planted at any 
season. The Philadelphia market gardeners begin to sow 
radish seed in cold frames in February ; though March is a 
more favorable month, on account of increased sunshine. 
The long radishes require more time to mature than the 
globular sorts, and are not so profitable under glass on that 
account. 
When not grown as a regular crop the radish is often 
used as a minor or catch crop; that is, a crop to occupy the 
ground during the growth of something of more importance. 
They are thus grown in forcing houses, among cucumbers, 
and in cold frames, between rows of carrots or beets. 
Or the radish may be grown as part of a succession of 
crops, as our 1896 note books indicate. There we have an 
account of a market gardener who starts in early fall, gets 
two crops of radishes, one of lettuce, one of tomatoes, and 
one of cucumbers, making five crops in all, covering the 
whole year in the operation. This work is done in a sash- 
covered forcing house, where the glass is removable in mid- 
summer. 
The wholesale market price of radishes at Philadelphia 
in winter may be quoted at $2 to $4 per 100 bunches. Of 
the red sorts it requires ten or twelve to make a bunch, and 
of the white sorts six or eight to a bunch. 
In giving the place of second importance among winter 
crops to this vegetable it must be understood that the market
