October, the ground is dressed and cleaned by
successive ploughings and weedings, and manured to the extent which
the means of the cultivator will permit. In the final preparation of
the land in October and November, the soil, after being well loosened
and turned up by the plough, is crushed and broken down by the passage
of a heavy log of wood over its surface, and it is in this state ready
for sowing.
The amount of produce from various lands differs considerably. Under
very favorable circumstances of soil and season, as much as twelve or
even thirteen seers (26 lbs.) of standard opium may be, obtained from
each biggah of 27,225 square feet. "Under less favorable conditions
the turn-out may not exceed three or four seers, but the usual amount
of produce varies from six to eight seers per biggah.
The chemical examination of different soils in connection with their
opium-producing powers, presents a field for profitable and
interesting inquiry; nor is the least important part of the
investigation that which has reference to variations in the
proportions of the alkaloids (especially the morphia and narcotine),
which occur in opium produced in various localities. That atmospheric
causes exert a certain influence in determining these variations is
probable; that they influence the amount of produce, and cause
alterations in the physical appearance of the drug, are facts well
known to every cultivator: thus the effect of dew is to facilitate the
flow of the juice from the wounded capsule, rendering it abundant in
quantity, but causing it at the same time to be dark and liquid. An
easterly wind (which in India is usually concomitant with a damp state
of atmosphere), retards the flow of juice, and renders it dark and
liquid. A moderate westerly wind, with dew at night, form the
atmospheric conditions most favorable for collection, both as regards
the quantity and quality of the exudation. If, however, the westerly
wind (which is an extremely dry wind) blow violently, the exudation
from the capsules is sparing. Whilst the effect of meteorological
phenomena in producing the above results are well marked, their action
in altering the relative proportions of the chemical constituents of
the juice of the poppy plant is more obscure, and it is highly
probable that the chemical composition of the soil plays a most
important part in this respect. Dr. O'Shaughnessy is certainly the
most accomplished chemist who had ever, in India,
