DIORAMA OF CHRISTIAN MISSIONS, 32, Sloane Street, will continue open for a short time. Parents will find this a truly Christian exhibition for their children. Tahiti--New Zealand--The Maori--Island of Tanna--Death of Captain Cook--First Missionary House at Tahiti--Cape Coast Castle--Banyan Tree--Ashanti--Missionary Tombs--The Dungeon, and Rose Madiai. What this exhibition wants, in order that it may enlist the sympathies of those who are the most earnest promoters of Missionary enterprise, is the addition of a few views of certain savage and heathen regions, the conversion and civilisation of whose inhabitants are more particularly important to the British public. The New Cut, Ratcliff Highway, Houndsditch, Whitechapel, and the slums of Westminster, afford fields for the operation of preachers and philanthropists as extensive, as remarkable, and as unknown as the Polynesian Archipelago or the Cannibal Islands. * * * * * DIETETIC RULE OF CONDUCT--Never ask a favour of a man until he has had his dinner. * * * * * [Illustration: A PHOTOGRAPHIC PICTURE. Old Lady (who is not used to these new-fangled notions). "_Oh, Sir! Please, Sir! don't, Sir! Don't for goodness sake Fire, Sir!_"] * * * * * WHAT IS A MILE? We think that the question of "What is a Mile?"--a question which promises to swallow up in interest the Eastern Question, and all other questions which as yet remain unanswered--should be settled as soon as possible; for, until it is settled, we shall never be able to arrive at a proper settlement of the Cab fares. This settlement is due--not only to the persons who ride in cabs--but to those who drive them, for there are so many varieties of a mile, and so many different ways of measuring it, that it is impossible to say which is the right one. For instance-- If a young lady walks round the corner of the street in which she lives, she comes home quite fatigued, and "is sure she has walked more than a mile." If a husband is dragged--a little against his will--to a certain street where there happens to be a bonnet shop, though it is not more than twenty yards, he is morally certain "he has been taken a mile out of his way, if he has been taken an inch." It is curious the number of miles a mother-in-law has walked when she feels desirous, poor creature, of having a cab.
