the use of its only fitting key. The complications of the lock were too much for those three philosophers, wise as they were in many things.

Our key shall be simply a rod, fifty inches in length. This key, simple as it appears, will unlock the Great Pyramid! We know the combination of at least the greater part of the wards, and will apply our Key to the whole with as much certainty as the cashier of "The *First National" applies his simple, straight steel slip to the crevice in the mighty iron door that nightly interposes itself between an unfriendly world and the treasures in the bank-vault. For convenience, we will have our rod jointed in the middle, and the whole subdivided into inches.

But why a rod of fifty inches? Of what grand measure is this a Metron (measuring-stick)? Reader, this is the metron that measures the world! When "the LORD answered JOB out of the whirlwind," He announced the fact that HE laid the foundation of the earth, that HE laid the measures thereof, that HE stretched the line upon it. In all these operations He may be said, figuratively, to have used this metron of fifty inches that we now hold in our hands. For this rod is an integral part of the earth's axis of rotation! Of that old and primal unit of measure, an inch, the earth's axis of rotation contains five hundred millions; and this metron of ours (a primal metron, "a grand standard," as the Astronomer Royal of Scotland loves to call it,) is the one ten-millionth part of that. Hold it up towards the north pole, then towards the south pole, then lay it meridian-wise between the poles and say, "Ten million such metrons as this will measure you exactly." Wonderful! But we have scarcely begun to appreciate the merits of our measuring-stick. With this metron MOSES measured the timber and the cloth of the Tabernacle, and the ground on which the Tabernacle and its enclosures stood. With this he measured the Ark of the Covenant. SOLOMON used it five centuries afterwards, for all his work. ZERUBBABEL, five centuries afterwards, used this metron for his Temple purposes; and so did HEROD, five centuries still later, for his. Nay, every Jewish synagogue in the world has its foundations laid, its timbers measured, and all its proportions justified by this metron, or rather by its half of twenty-five inches, which is the Sacred Cubit of the Jews.

This, then, is the metron by which the Pyramid-builders worked.— At the four corners of their proposed monument, they cut hollows carefully, truly, and deeply into the rock-hollows still identi

fied-and laid their basal corner-stones exactly 183 metrons (of fifty inches each) apart. Let us walk again around the Great Pyramid no light promenade, by the way: more than half a mile! and as we

pass

the four corners recall the suggestive fact that the master-builder of forty-three centuries" lang syne" laid down his metron for the guidance of the Egyptian workmen, 183 times on each side!

And at the very hour when the corner-stones were laid, it was ordained for the government of the overseers that the height of the Great Pyramid was to be one hundred and sixteen and one-half of these metrons, of which the base is 183. For the law of this structure is that the height, compared with twice the base, shall be as the diameter to the circumference of a circle." It was all constructed in the brain of the master, even before the sockets at the corners were cut, or the hill leveled off, or yonder quarries opened at Massarah, twelve miles south-east, on the other side the Nile. He saw it, every side a perfect plane, formed by the polished surfaces of the beveled casingstones, and those sides continued up to their mutual intersections, until terminated in a point. He saw it a thing of Fives a solid of five sides, including the basal plane; with its five chambers of construction, five angles, and, in short, a structure in which everything should go by fives, or numbers of five, and powers of five.

Is there not something thrilling and grand in the prescience with which an architect builds a great edifice on the tablets of his soul, and then upon the surface of his paper, even while the timbers are still growing in the forests, and the ore, the clay, and the stone lie all undisturbed in their native beds? He sees it by the eye of faith. stands looking over what to us is a vacant spot; but to him there is a tangible building, soaring in noblest proportions towards the sky, which occupies and adorns it. How MILTON revels in this thought, applying it to the Divine Builder, when preparing to people chaos with innumerable worlds!

Something of this faney will naturally occupy and kindle our thoughts as we stand, metron in hand, after considering the mighty base of 183, and the height of 116.5, of the Great Pyramid. If the master builder knew, as we do, that his rod bore such an exact propor tion to the size of the earth, it would account for the religious and astronomical coloring that we shall detect when we enter, as we will presently, the interior of the building, and begin to examine its vital

THE mathematics logically take the lead as the great and indispensable foundation of all learning. It is not only impossible to dispense with them, but impossible to place them anywhere else than at the beginning of all intellectual education. There can not possibly be any intellectual life whatever upon our planet, which does not begin with a perception of mathematical truth.-Dr. HILL.

Not how to live in the mere material sense only, but in the widest sense. The general problem, which comprehends every special problem, is the right ruling of conduct in all directions, under all circumstances what way to treat the body; in what way to treat the mind; in what way to manage our affairs; in what way to bring up a family; in what way to behave as a citizen; in what way to utilize all these sources of happiness which nature supplies; how to use our faculties to the greatest advantage of ourselves and others; how to live completely. And this, being the great thing needful for us to learn, is by consequence the great thing which education has to teach. To prepare us for complete living is the function which education has to discharge; and the only rational mode of judging of any educational course, is to judge in what degree it discharges such function.-Selected.

IT IS about time that one false etymology should get its quietus.Educate does not mean draw out."" The truth which this unscholarly philology has been so often invoked to teach is well able to stand up by itself. It needs no such questionable support. There are two Latin words educo · one of the third conjugation, and one of the first. Our "educate " comes from the latter, of course; the plain meaning of which is to bring up," "to rear," The derivation is from the idea of leading a child up from his childhood to maturity. It has nothing whatever to do with the refinement about educing what is in the mind. The Independent.

FOR stern, close thought, the mind must be schooled by habits of close application, and these are more rare than one would imagine.— Notwithstanding what is called application' in our public schools, the mind is generally so little exercised in it that few ever learn how to isolate themselves from present objects enough to think really, and the habit, if acquired, is easily lost.-C. CORNWALLIS.
