"You have the worst of it, son. Experience is a great teacher, they say. Let it help you not to do such a foolish thing again."

Theo met his father"s eyes gratefully. He still felt weak and shaken and he was thankful not to have his fault rubbed in.

During the long hours of the long days that followed the lad had many an opportunity to put his unselfish resolutions into practise. He insisted that his father and Mr. Croyden go off on the long tramps they had each season been accustomed to take together, and during their absence he remained with Franz, who was very kind to him. The Indian had a great many devices for entertaining him. Now he fashioned for the boy"s amus.e.m.e.nt a miniature birch-bark canoe; now he showed him how to weave baskets from lithe twigs of alder. Sometimes he whittled wonderful whistles and toys from bits of wood; sometimes made tiny bows and arrows or snowshoes. His resources seemed never ending.

Then when night came and Dr. Swift and Mr. Croyden returned from fishing Theo was always carried into the living-room of the cabin, and while he lay on the couch before the fire he would listen to the tale of the day"s adventures. This bedtime hour was the best in the whole day.

At last there came a morning when Theo awoke to hear a storm beating noisily down upon the roof. The wind was blowing hard and sheets of rain drenched the windows.

"There"ll be no fishing to-day," announced Dr. Swift after breakfast. "Instead Manuel is going out over the carry for provisions, and before he goes I must write some letters for him to take. In the meantime Mr. Croyden wants to know if you would like to have him come in and talk with you for a while?"

"Like it!" was the delighted exclamation.

"I believe I hear him now. Yes, here he is. Come in, Croyden!" called the Doctor heartily. "Our patient says he will be glad to see you."

"Glad? I should say I should!"

Mr. Croyden chuckled.

"I don"t know that any audience ever gave me such a royal welcome before," he declared with amus.e.m.e.nt. "How do you find yourself this morning, sonny? Able to talk Greek pottery?"

"Able to hear you talk it," Theo answered instantly.

"I am thinking of shifting my subject to-day and telling you about Chinese and j.a.panese pottery instead."

"That will be fine."

"Very well, we"ll begin our lecture right away, since the audience seems to be a.s.sembled," observed Mr. Croyden merrily. "Not only have you a private physician but a private lecturer, you see. My, but you are a royal personage! One thing will be very satisfactory about this audience. No matter whether it likes my talk or not it can"t run away."

There was a peal of laughter from Theo.

In the meantime Mr. Croyden poked the fire into a blaze and sitting down in a comfortable chair began his story.

CHAPTER IV

MR. CROYDEN"S STORY

"Hundreds and hundreds of years ago," said Mr. Croyden, "while the Egyptians, a.s.syrians, Greeks, and Romans were experimenting at pottery-making, the Chinese, inside their great walled country, were busy with the same task. In fact as far back as two thousand years before Christ the Chinese were famous potters, making earthenware of such fine quality that it was difficult to tell whether it was pottery or porcelain. For the two are quite different, you must remember, Theo. It is not enough to say that pottery is thick and porcelain thin, for much of the Chinese and j.a.panese pottery is very thin indeed. The difference lies in the clay itself, of which the ware is made. Do not forget that. Pottery is an opaque ware composed of various combinations of clay which afterward may or may not have a coating of glaze put over it. But genuine porcelain is made from a mixture of quite different materials--a mixture of decomposed feldspar known as kaolin, and petuntse."

Mr. Croyden paused a moment.

"There are of course so-called porcelains made from other ingredients; but we call them soft paste chinas, and do not rate them as true porcelains. Only a hard paste, or kaolin ware, is acknowledged by experts to be genuine porcelain. Now all this sounds very simple. By putting the kaolin and the petuntse together in the right proportions, moulding the clay, and afterward applying to it a glaze of some sort the Chinese made their porcelain, and very beautiful porcelain it was. Some day I will tell you more about it. This porcelain was not only very hard but was semi-translucent; by that I mean that if it was held to the light one could see the glow through it. It was not, of course, transparent like gla.s.s. These two qualities of hardness and translucence help us to distinguish porcelain from pottery."

Again Mr. Croyden stopped.

"For example, Canton ware, commonly known as Canton china, is not really china at all, but is instead a fine quality of stone, or earthenware, coated over with a slip or glaze containing porcelain.

Nor is the exquisite Satsuma ware china; that too is a pottery."

Theo listened intently.

"Now all this time the Chinese kept the secret of how they made their wares to themselves, not sharing their knowledge with any outside peoples. Many a nation would have given almost anything to know from what materials the beautiful bowls, vases, and dishes were made. It would have saved years and years of the toil of patient men. But the Chinese had no mind to tell any one. Instead, they went on making more and more pottery and porcelain, improving their work with each successive generation. It is amusing to recall that while our ancestors in England were barbarians, and were eating out of the crudest clay vessels or from trenchers of wood, the Chinese were enjoying the luxury of the finest pottery and porcelain."

Theo"s eyes opened very wide.

"Undoubtedly the Chinese deserved the good results they obtained, for they selected their clays with extreme care; ground and mixed them most skilfully; modeled each piece with the keenest feeling for its beauty and perfection; and decorated it in a truly artistic spirit.

"In the meantime they constantly became more and more expert. They began to learn the use of colors, and to perfect them. Some of the blues or cobalts they employed have never been surpa.s.sed. One for instance is the blue used on their Nankin china, and known as Nankin blue."

"Did the j.a.panese make pottery too?" questioned Theo.

"Yes, but we do not know exactly how early they began to make it. Probably some of the j.a.panese crossed to China and there learned the art. Some think pottery-making came into j.a.pan through Korea. However that may be, long before other countries had to any extent perfected the manufacture of glazed pottery and porcelain China, j.a.pan, Persia, and India had turned their attention to it. As far back as 1000 B. C. the j.a.panese were making porcelains similar to those of China. Then followed a long stretch of years when, because of various wars between China and j.a.pan, the art of producing glazed pottery and porcelain was lost. All those workmen who possessed any knowledge of their manufacture perished. This was the period when the Greeks and Romans were making their red and black ware which, you recall, they did not know how to glaze, and therefore had no means of preventing liquids from leaking through it."

"I wish they had had the secrets of the Chinese and j.a.panese!" Theo said.

"I wish so too," echoed Mr. Croyden. "As it was, they struggled along with their beautiful pottery vases through which the water percolated just as it does through a flower-pot. And so it was for a time in China and j.a.pan. It was not until centuries afterward that the Chinese and j.a.panese again rediscovered the art they had lost, and by that time the Greeks and Romans were no more, newer races having taken their places. Some of the wonderful old enamel work of the Chinese, however, was never reclaimed, and rare pieces of porcelain of a kind no one has yet been able to reproduce remain to tell us of the skill of those ancient Chinese workmen."

"If the Chinese kept everything so secret how did the art of glazed pottery-making ever get into Europe?" asked Theo.

Mr. Croyden smiled.

"It was a marvel that it ever did," he answered slowly. "Of course as people traveled little in those days one country did not know much about what another was doing. But there were wars when much booty was carried from one land to another; the pilgrimages of the Crusaders, too, helped to spread a knowledge of widely separated sections.

Gradually bits of Chinese pottery and porcelain found their way into different parts of the East; and as a consequence men began to be highly dissatisfied with their red and black ware, and with the crude clay dishes they had previously thought so fine. They wanted to make white ware like that of the Chinese. But because they did not know what clays to use, or how to glaze their products, all their experiments failed. There did nevertheless appear throughout the Orient a ware of common clay over which a simple covering of white had been painted, and this slip or engobe of white gave to the variety the name of Oriental Engobe. This type of ware decorated with a conventional dull-hued design was many years later revived and imitated by Theodore Deck of Paris, one of the great French porcelain makers. But even this was not like the white Chinese ware everybody wanted so much to make."

"Did they never find out the secret?"

"Of that I will tell you some other time. It is a most interesting story," returned Mr. Croyden. "In the meantime the Moors and Arabs who had lived in the Orient had in some way learned that tin or lead could be used for enameling clay surfaces. The discovery apparently did not particularly interest them because, you see, in the East minerals were not plentiful. When, however, in the twelfth century they conquered Spain they found in that country quant.i.ties of lead and tin, and they then recalled that these could be used as a glaze for pottery. In consequence they promptly set to work making an enameled ware called Majolica or Maiolica from the Island of Maiorca.

These Moors were a highly cultured race who built in Spain beautiful temples and palaces, among them the Alhambra, of which perhaps you have read."

Theo"s eyes shone.

"We read about it at school!" he cried.

"I am glad to hear that," exclaimed Mr. Croyden. "Then you will remember what a wonderful structure it was. In its interior have been found many highly glazed tiles beautifully designed and decorated in colors and in gold. Within this palace, too, was found the famous Alhambra Vase, three feet four inches in height, and made in 1320. It is a piece of work quite different from anything the Greeks made, but in its way is quite as perfect. It is of earthenware, with a white ground, and is enameled in two shades of blue with a further decoration of gold or copper l.u.s.tre. I speak particularly of this use of glaze because it is very important. Until people knew how to glaze their wares many of the comforts and conveniences of living were impossible. Men carried water or wine in leather gourds, or in clay vessels coated on the inside with a layer of gum to prevent the contents from leaking or evaporating."

"I should think the gum would have made the liquid taste," said Theo.

"It did. That was precisely the trouble. Beside that think of the waste. Suppose you lost half the water you needed for your journey by having it evaporate. Think in addition what it meant if a large part of your food dried up in the cooking."

Theo looked grave.
