pages to giving advice and more and more pages to pointing out the things that he would like to know before expressing opinions on practical issues. He has become, as a rule, an indefatigable and modest truth-seeker, irritating the busy folk who hurry from job to job on the top of the 'bus by his habit of sitting on the fence and replying to political questions by propounding new and often terribly unanswerable ones. He has recently re-christened his subject "Economics," to make it rhyme with the established sciences, Physics, Mathematics, Logic; and has become primarily a scientific enquirer, seizing on facts wherever he can find them. In his work of investigation he is at rather a disadvantage as compared with most scientists, because he can seldom perform crucial experiments. The experimental psychologist can subject people in the laboratory to various forms of sensory stimulisights, sounds, pin-pricks, electric shocks-and measure and tabulate results. The social psychologist (the economist) has usually to wait for statesmen, philanthropists, company promoters, to supply the appropriate stimuli; and then observe, as best he can, how his fellow-mortals behave under, say, the pin-pricks of an insurance act, the electric shock of a tariff, and so forth.

Our ship is anchored safe and sound-the voyage closed and done." But the reader, it is hoped, if he has taken no such trial trip before-it was the novice whom we invited to come with us -will scarcely be content with a single excursion round the world and back again. Luckily there are whole fleets for journeys of this kind, built and perpetually a-building. The economists' shipyards are for ever resounding with the clangour of work

men, and boat after boat splashes down each year from the builders' slips. For those who wish to take the round trip-the circular tour of the whole economic world-with more time to linger for sightseeing at the various ports than we have been able to arrange Professor Marshall's Economics of Industry, Dr. Cannan's Wealth, Professor Hadley's Economics, and Mr. P. H. Wicksteed's The Common Sense of Political Economy-may be recommended as seaworthy vessels less likely than others to bring him the discomforts incidental to most novices' first ventures away from dry land. For more special excursions there may be mentioned Mr. W. T. Layton's Capital and Labour, Sir W. H. Beveridge's Unemployment, Mr. Thiselton Mark's Efficiency Ideals, Professor Jenks' The Trust Problem, and Dr. Cassel's The Nature and Necessity of Interest; while for those who will only consent to sail under a captain who cracks jokes and tells breezy stories all the way, there is Mr. Hartley Withers' flotilla, Stocks and Shares, Money Changing, and The Meaning of Money. Another captain, with whom all his passengers speedily find themselves on the friendliest terms, but whom most economists hesitate to consider a full member of the regular service (as he has always his own private notions of the relative importance of the different elements that make up the art of economic navigation and of the best way to take one's latitude and longitude when out of sight of land), is Mr. J. A. Hobson, whose flag flies from a multitude of craft of all shapes and sizes.

These are only a small selection, chosen for the benefit of the untravelled novice. There are multitudes more on which the professional student is for ever embarking, stepping ashore from one,

only to set forth without delay upon another, once more on his adventure brave and new.' For travel of this kind grows in its absorbing interest with each new continent discovered.

"And come I may—but go I must—and if men ask you why, You may put the blame on the stars and the sun and the white road and the sky."

Once having begun we can never contentedly rust unburnished" among the home-staying folk ashore. Always we must follow the flying vision of Truth-regardless alike of the protests and the prejudiced outcries of hide-bound defenders of tyranny-begotten rights of property" and of tub-thumping advocates of cloud-begotten" inalienable rights of man." There is no end to the material to be studied, no end to the list of possible excursions. But if the novice likes our own method of travelling it is possible that we may organise a second trip on the same lines, and take observations of such things as coins and cheques, bulls and bears, taxes and tariffs. "Round many western islands shall we go, which bards in fealty to Apollo hold." Like most economists, however, the writer prefers not to make any definite prophecies.
