of ground, these come very expensive. A bell glass, pro- 
pagating glass, or ‘‘cloche”’ is shown in Fig. 77. 
A very handy contrivance, answering much the same 
purpose as handlights, but much less costly, and even more 
useful, is easily constructed by a handy 
man, with some strips, or battens, of 
sound deal and other wood, and squares 
of glass. This is illustrated in Fig. 78, 
which almost explains itself, and the 
affair is easily put together. It should ~ 
be made in 4ft. to 6ff. lengths, with 
moveable ends, so that any number may be placed end 
to end, as necessary. These will be found excellent for 
protecting rows of early peas, dwarf beans, etc., as 
well as for young lettuce, cauliflower, and other plants. 
Shading.—Many kinds of greenhouses and stove plants, 
of a somewhat delicate nature require to be screened in 
some way from the scorching rays of the sun in the 
summer season. Such subjects as the tuberous-rooted 
and other begonias, gloxinias, streptocarpus, most orchids, 
ferns, etc., must be shaded from 
strong sun or their beauty is soon 
destroyed, and even the foliage 
suffers, while tne blossoms of many 
other greenhouse-plants, including 
even the sun-loving geraniums, 
may be preserved in freshness and 
beauty for a considerable time by means of a light 
‘shade. 
The simplest and most common method of shading is to 
brush a little whitewash, or something of the kind, over the 
FIG, 77.
