THINNING CROPS. 
A great many seeing an Apple or Pear 
tree almost breaking down under the 
weight of its fruit are under the impres¬ 
sion that there will be a lot of fine fruit 
if all are allowed to hang, but this is a 
great error and mistake. If these fruits 
were thinned gradually, one by one, from 
each spur, as they advanced in size, there 
would be much finer fruit of a much 
greater value than the overbearing crop 
complete. The fruit should be removed 
one by one until only one remains to 
each spur, as it must be borne in mind 
that each spur was only meant to carry 
one or two fruits, and that if trees were 
properlv thinned each year, countless 
numbers of barren spurs would, as time 
advanced, become fruitful. 
The same thinning necessarily applies 
to vegetable crops of all descriptions. 
For example, Cabbage seed sown thickly 
and left in the bed till planting time 
arrives • will produce long, weakly, tap- 
rooted varieties, that will take no end of 
manure and never turn to good account. 
These should be transplanted into a bed 
six inches apart as soon as the seedlings 
are fit to handle. Onions, Parsnips, 
Beetroot, and all such vegetables are 
benefited by timely thinning.

(Nephro'epis exaltata elegantissima.) 
When once the species of Nephrolepis 
begin to vary by the extended ramifica¬ 
tion of their pinnae, there seems to be no 
limit to the extent to which they may 
divide, except that the mass of moss-like 
Fern leaves produced so obstruct the

spaces between the nodes had elongatec 
so as to allow the pinnae to retain thei 
usual or original vertical condition. A 
it is, however, the plant is of moderati 
dimensions, compared with the materia 
in it, and the effect is handsome as wel 
as remarkable. 
The larger illustration shows a singh 
frond of N.e. elegantissima, but reader, 
may more readily grasp an idea of thi 
alteration which has taken place by look 
ing at the illustration consisting of thref 
fronds placed side by side. The firs' 
frond on the right represents N. exaltats 
or the Boston variety of it. The middle 
frond shows N.e. Piersoni, in which the 
upper three-fourths of each pinna i: 
widened greatly, becoming bipinnate in¬ 
stead of being simply pinnate as in the 
other frond alongside of it. In No. 3 to

light as to make fresh division practically 
impossible. The fronds of this form are 
practically three times divided, and owing 
to the great width of the pinnae it was 
necessary for them to turn round hori¬ 
zontally instead of being vertical to the 
earth's surface. This form of growth has 
made the surface of the frond appear like 
a dense mass of moss, and if the frond 
is looked at sideways it is then seen to be 
about an inch in depth instead of being 
of the ordinary thickness of a Fern frond. 
There is material enough in this Fern to 
the left (N.e. elegantissima) the pinnae 
have greatly increased in length, but 
have undergone a gradual division, while 
still having little more than the space 
allowed to the original. We thus see 
a very complicated frond may be de¬ 
veloped from a very simple one. Those 
who are not acquainted with these facts 
would not recognise the ultimate form asi 
being any relation to the original. 
Besides these forms there is ano.hei 
one, namely, N.e. todeaoides, in w.rich 
the process of division has .gone a little
