St. John saw this City suspended in the air, he therefore had a clear view of its twelve foundations and the names of the twelve Apostles of the Lamb, and the twelve gates, and the names written thereon, which are the names of the twelve tribes of the children of Israel. "And he measured the wall a hundred and forty and four cubits," two hundred and sixty-two and a half feet, and they were studded with all kinds of precious stones, and diamonds from the bowels of the earth, while the gates are adorned with the treasures of the ocean. Now this beautiful description of the City is given in the twenty-first chapter, from 16 to 18 and 21st verses. We must keep it distinct from the walls. He says, it lieth four square, and measures twelve thousand furlongs. This sum, divided by eight furlongs, which make a mile, would stand thus: 8/12000--fifteen hundred miles square or seven millions nine hundred and twenty thousand feet on six sides (it being a cubical form.) When we look at the size of this _City_ of Gold, we are at once almost overwhelmed with the view of its dimensions. Fifteen hundred miles high, long and wide! In the seventeenth verse, he gives but one way to measure the wall, and that is its height. If he had undertaken to have given the contents of the City by the same rule, he would have measured the wall. Then we have nothing more to do in making an arithmetical calculation, but follow the Apostle's description. Jesus said, in my Father's house are many mansions. Now, allowing twelve feet between joints for a story, this seven millions nine hundred and twenty thousand feet square would give six hundred and sixty thousand stories, twelve feet high, (Ezekiel xl: 7,) and fifteen hundred miles square, four hundred and forty stories to a mile: which would amount to 990,000,000, nine hundred and ninety millions of square miles on a level surface, twelve feet high--equal to the square miles contained in five worlds like this, (which is only one hundred and ninety-nine millions five hundred and twelve thousand square miles,) and seventy times more extensive than the Continent of America. Now six hundred and sixty thousand twelve foot rooms in each story, would make in all 435,600,000,000--four hundred and thirty-five thousand and six hundred millions of twelve feet square "rooms,"--_Ezekiel_; "places,"--_John_; or "mansions,"--_Jesus_. It is computed that there are 900,000,000--nine hundred millions of inhabitants now on the Earth. The Bible informs us that there was but one, six thousand years ago. Admit that there was nine hundred millions at the commencement of creation, and this number had passed away every thirty years for two hundred generations, their whole number would only amount to 180,000,000,000--one hundred and eighty thousand millions, a little more than one-third of the mansions in this building; four hundred and eighty-four to every human being now on the earth. Surely, this looks
