which the sap-vessels are adapted to warmer climates : hence the difficulty of 
acclimatising plants. 
Some kinds of Apricot are more hardy than others. The Breda and Turkey 
are less liable to decay than Anson’s, or the Moorpark, which is said, to have 
been introduced by Admiral Anson. I wish, however, to notice, that the 
gangrene in the inner bark is the effect of ruptured sap-vessels. In general 
the decay begins near the clefts of the branches, close to the main stems, and 
in time checks the supplies from the roots, it matters not whether the trees 
are young or old. Perhaps the evil may in some measure be prevented by 
keeping the outer bark smooth to throw off the wet, and by protecting the 
suspected parts with fern during winter.

REMARKS ON THE GENUS MYOSOTIS. 
All the perennial species of this genus are very beautiful, and well deserve 
to be extensively cultivated. They grow best in moist situations, or by the 
edges of ponds or ditches. They may also be grown in any place in the garden 
not too hot or dry ; or they may be cultivated in pots. They are easily increased 
by division of the roots, and by seeds. The seed should be sown in the autumn 
upon an open bed or border of light earth. In the spring the plants should be 
thinned where they are too close. If the ground where the plants are to be 
grown be kept clear of weeds and the seeds be permitted to scatter, an abund¬ 
ance of plants will spring up without further trouble. Large masses near 
walks through plantations are very effective. In such places they require no 
attention further than keeping them clear of weeds. The following are very 
beautiful:— 
Myosotis azorica .—This is a very fine hardy species from the Azores, with 
heads of rich purple, changing to deep blue. It is found in damp ravines, and 
generally near waterfalls. Well worthy of extensive cultivation. 
Myosotis montana (the Spring Forget-me-not).—This is a very fine species 
from Norway and Switzerland. It blooms with the melting snow, frequently 
with the Snowdrop, Aconite, &c. The flowers are larger and brighter than 
those of the Wood Forget-me-not (M. sylvatica). It should be grown ex¬ 
tensively- 
Myosotis pcilustris .—A very valuable species on account. of its long-con¬ 
tinuing autumn bloom. 
Myosotis rupicola (the Perennial Alpine Forget-me-not).—This is a very 
beautiful species. Its large heads of deep and brilliant blue, fragrant flowers 
render it a very striking object. The individual blossoms are nearly circular, 
and frequently have a yellow eye. It does best in shady fissures, or on ledges 
with a northern aspect. It blooms late in spring. It should be very largely 
grown.

ON THE CULTIVATION OF THE FILBERT. 
Whatever differences of opinion may exist respecting the management 
of most of our hardy fruits in regard to the amount of pruning they require, 
there is no question that the knife, or it may be the saw, is more freely used 
in the treatment of this tree than in that of any other. It is not too much to 
say that in the case of the Filbert fully nine-tenths of every year’s growth are 
cut away, and often more than that; and, if we except the Vine when pruned 
on the spur system, there is certainly no other fruit tree on which the knife
