It will be seen on the diagram below that seven straight vertical cuts with a table-knife will divide a crumpet into twenty-eight parts.
BALANCE THE SCALES
The nine digits can be so adjusted as to form an equation, or, if taken as weight, to balance the scales. Thus:—
9, 61⁄2 = 3, 5, 74⁄8
TRUE STRETCHES OF IMAGINATION
How large is the sea? This is a bold big question, and any possible answer involves a considerable stretch of the imagination. Here is a startling illustration of its vast volume:—
If the water of the sea could be gathered into a round column, reaching the 93,000,000 miles which separate us from the sun, the diameter of this column would be nearly two miles and a half!
It is perhaps even more difficult to realise that this mighty mass of waters could be dissipated in a few moments, if the column we have imagined could become ice, and if the entire heat of the sun could be concentrated upon it. All would be melted in one second of time, and converted into steam in eight seconds!
