One of the commercial questions of the day which remains to this time unsettled, is whether the fact of a gentleman having NO TIN may not have something to do with the answer he invariably sends of NOT IN when anyone calls on him with a bill. 78. Find nine numbers in arithmetical progression--common difference 3--whose sum is equal to 5670, and arrange in a square, each side containing three different numbers, so that, when added vertically, horizontally or diagonally, the sum of each three numbers will amount to 1890. 79. I have a box. The pieces forming the sides are 5 ft long, and those forming the ends are 4 ft. broad.

[Illustration] Teacher: “Who was it that supported the world on his shoulders?” Bright Pupil: “It was Atlas, ma’am.” Teacher: “And who supported Atlas?” Bright Pupil: “The book don’t say, but I s’pose it was his wife.” ON BOTH SIDES OF A DOOR IN A MELBOURNE OFFICE. THE MAN WHO FORGETS THE DOOR. Oh, there’s an individual who ev’rywhere abounds, Thro’ trains and shops and offices he makes his busy rounds, And in and out for ever he is going o’er and o’er, To keep somebody after him attending to the door! In sultry summer, when to catch a cooling breeze we’ve tried, And carefully have opened every door and window wide, ’Tis then you may be certain as he vanishes from sight, He’ll die but that he’ll shut the door--and close it very tight! But when the winds of winter come, with cold and biting breath, Oh, then it is the awful wretch is tickled ’most to death! His sense of pleasure reaches to a point that is sublime; He never fails to leave the door wide open every time! 80. A man agrees to work for £8 a year and a suit of clothes.

Place four 5’s so that they shall express 6½. “SHE” AGAIN. 84. The country spark that asked the charming “she” How many years of age that she might be, Again asked her to tell to him in haste How many inches she was round the waist. “My waist is such if multiplied by four, Four-fifths of product add on my age more, The square root of three-fifths of this is six: Now find my waist, and get out of this fix.” SOME LONG WORDS.
