provision chest. They were not injured in the slightest respect, thanks
to the means taken to counteract the shock. The provisions were in good
condition, and abundant enough to supply the travellers for a whole
year--Barbican having taken care to be on the safe side, in case the
Projectile might land in a deserted region of the Moon. As for the water
and the other liquors, the travellers had enough only for two months.
Relying on the latest observations of astronomers, they had convinced
themselves that the Moon's atmosphere, being heavy, dense and thick in
the deep valleys, springs and streams of water could hardly fail to show
themselves there. During the journey, therefore, and for the first year
of their installation on the Lunar continent, the daring travellers
would be pretty safe from all danger of hunger or thirst.

The air supply proved also to be quite satisfactory. The _Reiset_ and
_Regnault_ apparatus for producing oxygen contained a supply of chlorate
of potash sufficient for two months. As the productive material had to
be maintained at a temperature of between 7 and 8 hundred degrees Fahr.,
a steady consumption of gas was required; but here too the supply far
exceeded the demand. The whole arrangement worked charmingly, requiring
only an odd glance now and then. The high temperature changing the
chlorate into a chloride, the oxygen was disengaged gradually but
abundantly, every eighteen pounds of chlorate of potash, furnishing the
seven pounds of oxygen necessary for the daily consumption of the
inmates of the Projectile.

Still--as the reader need hardly be reminded--it was not sufficient to
renew the exhausted oxygen; the complete purification of the air
required the absorption of the carbonic acid, exhaled from the lungs.
For nearly 12 hours the atmosphere had been gradually becoming more and
more charged with this deleterious gas, produced from the combustion of
