"Strange, isn't it, how much of our knowledge of the ancient races has come down to us through their clay work?" he reflected. "What should we have known of these western civilizations save through their handiwork? And when we travel across seas it is the same. Much of our acquaintance with Egyptian, Greek, and Roman life has been handed down to posterity through tiles and pottery which have served to record nations' customs and advancement. The march of the invading Roman armies, for example, can be traced by the fragments of pottery left behind them. These relics have been found in England, France, Germany, Italy, and Spain, and prove that very early the Romans made use of clay utensils for cooking their food. Even beneath the city of London old Roman furnaces for firing dishes have been discovered; and moreover, some of the very dishes themselves."

Theo seemed astonished.

"Later the Romans made much beautiful pottery; but it was never as beautiful as that of the Greeks. Sometime, however, Theo, you should go to one of our museums and see some Samian ware, the finest of Roman clay work. The red in it is almost as vivid as sealing-wax, and it has a wonderful polish not unlike that on modern Egyptian ware. No one has ever been able to discover from what clay this marvelous pottery was made. Some historians think the ware was first made by wandering Greek artisans. The Romans also made a very beautiful black ware now known as Upchurch pottery because of the location in England in which it was found. This black color, scientists have decided, was not produced by mixing a pigment with the clay as did the Greeks, but resulted from an ingenious use of oxide of iron which, when burned by a reducing fire, turned black; the Romans also gave us Castor ware, a pottery moulded from a dark clay and having on it figures traced in a lighter color."

"Did anybody else in Europe make as beautiful pottery as the Greeks and Romans?" inquired Theo.

"Perhaps not so beautiful," answered Mr. Croyden. "Yet before we hear either of Greek or Roman we find the Egyptians and Assyrians, nations famous for their skill in the arts as well as their prowess in war, making pottery and tiles. These have been preserved to us in tombs and pyramids, for these races, you know, were accustomed to pay great honor to their dead. It was a fortunate custom, too, since by means of it much history has come down to us which would otherwise have been destroyed. Unquestionably the Saxons, Scandinavians, Gauls, and Teutons also made pottery, but their attempts were of a cruder sort. Dishes, vases, toys have been exhumed in their countries, all displaying characteristic clay designs. But no country in the world has ever equaled the pottery of the Greeks."

"Did the Greeks——" began Theo; but his father cut him short.

"See here, young man," he declared, drawing out his watch, "this is no time of night for you to be setting forth on a history of Greek pottery. You are going to bed.

"I HAD FORGOTTEN ALL ABOUT BED"

Theo rose with a laugh.
