experiments. About five hundred miles is the limit of a man's ignorance; he then knows enough to make trouble; at the end of another five hundred he is of assistance, at the end of the third he will run the machine himself—your greatest pleasure is in the first five hundred. With some precocious individuals these figures may be reduced somewhat.

The Professor adjusted his spectacles and looked at the machine:

"A very wonderful contrivance, and one that requires some skill to operate. From lack of experience, I cannot hope to be of much practical assistance at first, but possibly a theoretical knowledge of the laws and principles governing things mechanical may be of service in an emergency. Since receiving your telegram, I have brushed up a little my knowledge of both kinematics and dynamics, though it is quite apparent that the operation of these machines, accompanied, as it is said, by many restraints and perturbations, falls under the latter branch. In view of the possibility—remote, I trust—of the machine refusing to go, I have devoted a little time to statics, and therefore feel that I shall be something more than a supercargo."

"Well, you are equipped, Professor; no doubt your knowledge will prove useful."

"Knowledge is always useful if people in this busy age would only pause to make use of it. Mechanics has been defined as the application of pure mathematics to produce or modify motion in inferior bodies; what could be more apt? Is it not our intention to produce or modify motion in this inferior body before us?"

Days after the Professor found the crank a more useful implement for the inducing of motion.

It was Thursday morning, August 1, at exactly seven o'clock, that we passed south on Michigan Avenue towards South Chicago and Hammond. A glorious morning, neither hot nor cold, but just deliciously cool, with some promise—afterwards more than fulfilled—of a warm day.

The hour was early, policemen few, streets clear, hence fast speed could be made.

As we passed Zion Temple, near Twelfth Street, the home of the
Dowieites, the Professor said:

"A very remarkable man, that Dowie."

"A fraud and an impostor," I retorted, reflecting current opinion. "Possibly; but we all impose more or less upon one another; he has simply made a business of his imposition. Did you ever meet him?"

"No; it's hardly worth while."

"It is worth while to meet any man who influences or controls a considerable body of his fellow-men. The difference between Mohammed and Joseph Smith is of degree rather than kind. Dowie is down towards the small end of the scale, but he is none the less there, and differs in kind from your average citizen in his power to influence and control others. I crossed the lake with him one night and spent the evening in conversation."

"What are your impressions of the man?"

"A shrewd, hard-headed, dogmatic Scotchman,—who neither smokes nor drinks."

"Who calls himself Elijah come to earth again."

"I had the temerity to ask him concerning his pretensions in that direction, and he said, substantially, 'I make no claims or assertions, but the Bible says Elijah will return to earth; it does not say in what form or how he will manifest himself; he might choose your personality; he might choose mine; he has not chosen yours, there are some evidences that he has chosen mine."

"Proof most conclusive."

"It satisfies his followers. After all, perhaps it does not matter so much what we believe as how we believe."

A few moments later we were passing the new Christian Science Temple on Drexel Boulevard,—a building quite simple and delightful, barring some garish lamps in front.

"There is another latter-day sect," said the Professor; "one of the phenomena of the nineteenth century."

"You would not class them with the Dowieites?"

"By no means, but an interesting part of a large whole which embraces at one extreme the Dowieites. The connecting link is faith. But the very architecture of the temple we have just passed illustrates the vast interval that separates the two."

"Then you judge a sect by its buildings?"

"Every faith has its own architecture. The temple at Karnak and the tabernacle at Salt Lake City are petrifactions of faith. In time the places of worship are the only tangible remains—witness Stonehenge."

Chicago boasts the things she has not and slights the things she has; she talks of everything but the lake and her broad and almost endless boulevards, yet these are her chief glories.

For miles and miles and miles one can travel boulevards upon which no traffic teams are allowed. From Fort Sheridan, twenty-five miles north, to far below Jackson Park to the south there is an unbroken stretch. Some day Sheridan Road will extend to Milwaukee, ninety miles from Chicago.

One may reach Jackson Park, the old World's Fair site, by three fine boulevards,—Michigan, broad and straight; Drexel, with its double driveways and banks of flowers, trees, and shrubbery between; Grand, with its three driveways, and so wide one cannot recognize an acquaintance on the far side, cannot even see the policeman frantically motioning to slow down.

It does not matter which route is taken to the Park, the good roads end there. We missed our way, and went eighteen miles to Hammond, over miles of poor pavement and unfinished roads. That was a pull which tried nerves and temper,—to find at the end there was another route which involved but a short distance of poor going. It is all being improved, and soon there will be a good road to Hammond.

Through Indiana from Hammond to Hobart the road is macadamized and in perfect condition; we reached Hobart at half-past nine; no stop was made. At Crocker two pails of water were added to the cooling tank.

At Porter the road was lost for a second time,—exasperating. At Chesterton four gallons of gasoline were taken and a quick run made to Burdick.

The roads are now not so good,—not bad, but just good country roads, some stretches of gravel, but generally clay, with some sand here and there. The country is rolling, but no steep hills.

Up to this time the machine had required no attention, but just beyond Otis, while stopping to inquire the way, we discovered a rusty round nail embedded to the head in the right rear tire. The tire showed no signs of deflation, but on drawing the nail the air followed, showing a puncture. As the nail was scarcely three-quarters of an inch long,—not long enough to go clear through and injure the inner coating on the opposite side,—it was entirely practical to reinsert and run until it worked out. A very fair temporary repair might have been made by first dipping the nail in a tire cement, but the nail was rusty and stuck very well.

An hour later, at La Porte, the nail was still doing good service and no leak could be detected. We wired back to Chicago to have an extra tire sent on ahead.

From Chicago to La Porte, by way of Hobart, the roads are excellent, excepting always the few miles near South Chicago. Keep to the south—even as far south as Valparaiso—rather than to the north, near the lake. The roads are hilly and sandy near the lake.

Beware the so-called road map; it is a snare and a delusion. A road which seems most seductive on the bicycler's road map may be a sea of sand or a veritable quagmire, but with a fine bicycle path at the side. As you get farther east these cinder paths are protected by law, with heavy fines for
