lowed for the accomplishment of this great task, but
by diligence and promptness, John Aird & Co. were ready to pack up their
tools and come away a whole year sooner than was expected. His Royal
Highness the Duke of Connaught went to Assuan, in December, 1902, and
declared the great dam fit to begin its important duties.

And this is how those duties are performed. Early in July each year,
every sluice is opened to its widest, the iron doors being lifted as
high as they will go. The Nile at that time is seen to be rapidly
rising, and nothing must obstruct its passage. For five whole months it
is allowed to rush in growing volume on its course. By that time, the
rich deposit, of which we have spoken, has all passed through the
sluices, and the time has arrived for checking the clearer and less
turbulent water by which it is followed. The first gates are lowered
early in December, being of course those in the lowest part of the dam.
These are followed by fifty more on a higher level; and so on until all
the sluices are carefully closed, with the exception of some which are
left open for surplus water to pass through. The reservoir is not full
until the end of February, and thus takes three months to collect its
waters. But so vast is its extent, that the stoppage is said to affect
the river one hundred and forty miles farther south. The water thus held
back is not allowed to escape until May, when it is most wanted in the
fields below the dam; and it is, of course, all gone by the beginning of
July, when the sluices are gaping wide again to let the new floods pass.
It need hardly be said that the order just described varies a great
deal according to the moods of the river. The dam must be regulated to
those changing moods, or the benefits it gives could not be relied upon.
Thus from the fickle stream a constant blessing is drawn, and year after
year, with the shifting seasons, those stately gates will rise and fall;
the river channel will always have its water, so long as the gates last,
and there will be corn in Egypt.

GREY-SKIN'S ADVENTURES.

But for an undue affection on my part for fruit of all kinds, you would
probably never have heard my story; for I might possibly have been free,
and the happiest lives, they say, are those which have no history.

What happy times we had in that far-away land over the seas--the
gambols and
