The explanation of the efficacy of 
wr co stirring the soil about growing 
plants is based on the loosening 
and breaking up of the soil particles, in order to 
facilitate the progress of the roots, and admit the 
air which oxidises organic matters, and acts on 
the mineral substance so as to liberate the plant- 
food, to change the physical conditions of the 
soil with respect to evaporation and absorption, 
and, it may o change mechanically the 
` position of the plant-food within the interstices 
of the soil, and to facilitate the production and 
growth of roots. Intercultural tillage, therefore, 
is beneficial because it pulverises and stirs the 
be timed to the necessities of the plant. It is a 
means to an end, and judiciously employed pro- 
~ proper time, or a springtime which, with a hot 
DUM Sun by day to warm the earth, has coo ool nights to 
d the night сїз in somewhat of а 
we have flowers ap 
admired of | 
xcess of manure tends to hasten leaf-growth, 
especially if the manure is strongly nitrogenous; 
and hence if the plant be left to itself growth 
becomes rank, and there is little production of 
flower or fruit, If, however, the growth be 
properly checked. then the forces of leaf-growth 
are div mag to the production of flower, seed, and 
maturatio 
вап illustration, we can cite the Cabbage, 
which, in poor soil and in dry and hot seasons, 
will throw up prematurely the inflorescence, due 
in ordinary course the following year. And even 
in rich soils the Cabbage may be caused to break 
its head and send out a seed-stem, by judiciously 
checking its growth. e importance of these 
facts has long been recognised by horticul- 
turists. 
Thus, under the head of “resting,” LINDLEY 
states “that the effect of a very dry atmosphere 
is to inspissate the sap of the plant, and this in 
all cases tends to the formation of blossom-buds 
and fruit 'ery low temperatures, under t 
influence of much light, by retarding and 
diminishing the expenditure of sap in the growth 
of plants, comparatively with its creation, causes 
an early appearance of fruit.” Again,“ What- 
ever produces excessive vigour in plants i is favour- 
able to the formation of leaf-buds, and unfavour- 
abletotheproductionof flower-buds ; while,on the 
other hand, such circumstances as tend to diminish 
luxuriance and to check rapid vegetation without 
affecting the health of the plant are more favour- 
able to the production of flower-buds than of 
leaf-buds." 
It is quite evident that all plants must either 
send their roots to the food in the soil, or the 
food must go to the roots, or the two processes 
must be combined. In the passage of water in 
e an agency for the disturbance 
of the relations of the food supply. 
In the growth of the root we have another 
agency which brings the plant into contact with 
the food. Now it seems plain that that plant 
which occupies with its feeding roots the largest 
extent of soil, that plant whose roots fill the most 
interstices of the soil, must, other things being 
equal, have a greater command o ver the food 
supply of the soil. In root-pruning many plants 
we cause the main roots to divide, and send out 
more numerous small fibrils апа root-hairs than 
existed on the root that was cut away, and we 
thus give that plant a greater access to the d 
supply of the soil than it previously had; 
as, for illustration, we can increase t at joera o on 
a given area of a hedge, by a syste g 
which shall cause nia multiplication of 
branches within that a 
But on all plants the "beneficial ao of root- 
pruning and interculture would seem to be more 
marked on fertile land than on poor rede or even 
land in ordinary condition. Шш all cases it 
should be applied according to the physiological 
requirements of the plants with which we have 
to deal. 
AMARYLLIS COLONEL BURNABY.— The fig. (136), 
for which we are indebted to the kindness of Messrs, 
J. VEITCH & Sons, Chelsea, represents one of the 
est varieties of the new type of Amaryllis that have 
been raised by them by intercrossing the South 
American Hippeastrum pardinum and H. Leopoldi— 
which gave good form and substance to the flowers, 
but reduced their number -- with the best of the 
Amaryllis of Continental origin. These hybrids pro- 
duce from two to four blooms on a scape, whic 
large and usually of brilliant colours. It is also notices 
able that the segments of the flower are getting more 
and more bluntly pointed in the later forms, so ebd 
proaching the circular

scarlet in colour, of extra large size and substance, 1

Royal Horticultural Society and a Certificate of

the Executive Committee, who will discuss them in 
detail, and submi 
for approval previous to going before t a
