Covering for Greenhouses and frames _The Author of the 
Domestic Gardener’s Manual having, in a paper on Greenhouses, in¬ 
serted in the last Quarterly Agricultural Magazine, recommended 
a Temporary Covering of Oiled Canvass to be placed over Green¬ 
houses at night, and wishing to use something of the sort for Frames 
containing plants in the winter, I doubt not, from the readiness with 
which he endeavours to improve your readers, that he will oblige me, 
through your pages, by giving the necessary instructions for prepar¬ 
ing the canvass for use. H. C. 
Changing Seed Corn.— G. M. W. is informed, that the chang¬ 
ing of Seed Corn is very requisite, if judiciously considered, the 
higher land lies above the level of the Sea, the soil is not so fertile 
nor the climate so genial as low grounds; therefore if a clean sample of 
any grain can be obtained from high land, and sown on soil that lies 
lower, the grain will increase in quality and size for three or four 
years on that Farm. When the grain is observed to decrease, which 
it will do after the soil can improve it no further, another change as 
above should take place.— William Grey. 
To an enquirer, page 288, relative to the culture of Aquatics. 
Changing the water of Aquatics must depend on the situations in 
which they grow; if in pots placed in pans of water, they should 
be supplied twice or three times a week in summer, and once a week 
in winter. The best kind of soil for them is composed of bog earth 
(not peat) and loam, with a large portion of sand. The times of re¬ 
potting depends on the sorts and state of growth, once in a year for the 
generality of plants, is sufficient, and in some cases not oftener than two 
years. This should be done immediately after the flowering season. 
On no account pare the balls of roots with a Knife. 
Anagallis Webbiana. This plant never thrives if it be crow¬ 
ded amongst other plants. It is always better to strike young plants 
every year, the old ones seldom thrive well more than a year. Cut¬ 
tings taken off at three joints, and planted round the sides of a pot, 
and plunged in a gentle heat, will strike roots readily. 
Chrysanthemums. If the roots of Chrysanthemums are allow- 
ed to grow through the bottoms of the pots, they will when cut olf, 
greatly check the growth and flowering of the plants; this may pos¬ 
sibly have been the case with those named page 288, if so, the best 
plan is for the future to shift them into larger pots so often as they 
require it, and not to allow them to stand too long in one place with¬ 
out being moved.
