e with a wave of his hand. They
moves through the air together, but the earth is always nearest to the
sun and consequently once a fortnight the shadder of the earth falls on
the moon and darkens it so that it's invisible to the naked eye. The
new moon is caused by the moon movin' a little bit out of the earth's
shadder, and it keeps on comin' more and more until we gets the full
moon; and then it goes back again into the shadder; and so it keeps on.'

For about a minute everyone looked very solemn, and the profound
silence was disturbed only the the crunching of the biscuits between
the jaws of Mr Bosher, and by certain gurglings in the interior of that
gentleman.

'Science is a wonderful thing,' said Mr Sweater at length, wagging his
head gravely, 'wonderful!'

'Yes: but a lot of it is mere theory, you know,' observed Rushton.
'Take this idear that the world is round, for instance; I fail to see
it! And then they say as Hawstralia is on the other side of the globe,
underneath our feet. In my opinion it's ridiculous, because if it was
true, wot's to prevent the people droppin' orf?'

'Yes: well, of course it's very strange,' admitted Sweater. 'I've
often thought of that myself. If it was true, we ought to be able to
walk on the ceiling of this room, for instance; but of course we know
that's impossible, and I really don't see that the other is any more
reasonable.'

'I've often noticed flies walkin' on the ceilin',' remarked Didlum, who
felt called upon to defend the globular theory.

'Yes; but they're different,' replied Rushton. 'Flies is provided by
nature with a gluey substance which oozes out of their feet for the
purpose of enabling them to walk upside down.'

'There's one thing that seems to me to finish that idear once for all,'
said Grinder, 'and that is--water always finds its own level. You can't
get away from that; and if the world was round, as they want us to
believe, all the water would run off except just a little at the top.
To my mind, that settles the whole argymint.'

'Another thing that gets over me,' continued Rushton, 'is this:
according to science, the earth turns round on its axle at the rate of
twenty miles a minit. Well, what about when a lark goes up in the sky
and stays there about a quarter of an hour? Why, if it was true that
the earth was turnin' round at that rate all the time, when the bird
came down it would find itself 'undreds of miles away from the place
where it w
