study."
"I can understand that," replied Monsieur Roger; "but what a sorrow this exile must cause the mother of this child!"
"Paul has no mother: she died several years ago."
"Poor boy!" murmured Monsieur Roger, and his growing friendship became all the stronger.
That evening, after dinner, when coffee was being served, Miss Miette, who was in a very good humor, was seized with the desire to tease her little friend Paul.
"Say, Paul," she asked, from one end of the table to the other, "how many prizes did you take this year?"
Paul, knowing that an attack was coming, began to smile, and answered, good-naturedly,—
"You know very well, you naughty girl. You have already asked me, and I have told you."
"Ah, that is true," said Miette, with affected disdain: "you took one prize,—one poor little prize,—bah!"
Then, after a moment, she continued,—
"That is not like my brother: he took several prizes, he did,—a prize for Latin, a prize for history, a prize for mathematics, a prize for physical science, and a prize for chemistry. Well, well! and you,—you only took one prize; and that is the same one you took last year!"
"Yes," said Paul, without minding his friend's teasing; "but last year I took only the second prize, and this year I took the first."
"You have made some progress," said Miss Miette, sententiously.
Monsieur Roger had been interested in the dialogue.
"May I ask what prize Master Paul Solange has obtained?"
"A poor little first prize for drawing only," answered Miette.
"Ah, you love drawing?" said Monsieur Roger, looking at Paul.
But it was Miette who answered: "He loves nothing else."
Monsieur Dalize now, in his turn, took up the conversation, and said,—
"The truth is that our friend Paul has a passion for drawing. History and Latin please him a little, but for chemistry and the physical sciences he has no taste at all."
Monsieur Roger smiled.
"You are wrong," replied Monsieur Dalize, "to excuse by your smile Paul's indifference to the sciences.—And as to you, Paul, you would do well to take as your example Monsieur Roger, who would not have his fortune if he had not known chemistry and the physical sciences. In our day the sciences are indispensable."
Miss Miette, who had shoved herself a little away from the table, pouting slightly, heard these words, and came to the defence of the one whom she had begun by attacking. She opened a book full of pictures, and advanced with it to her father.
"Now, papa," she said, with a look of malice in her eyes, "did the gentleman who made that drawing have to know anything about chemistry or the physical sciences?"
CHAPTER VIII.
A DRAWING LESSON
For a moment Monsieur Dalize was disconcerted, and knew not what to say in answer. Happily, Monsieur Roger came to his aid. He took the book from Miette's hands, looked at the engraving, and said, quietly,—
"Why, certainly, my dear young friend, the gentleman who made that drawing ought to know something about chemistry and physical science."
"How so?" said Miette, astonished.
"Why, if he did not know the laws of physical science and of chemistry, he has, none the less, and perhaps even without knowing it himself, availed himself of the results of chemistry and physical science."
Miette took the book back again, looked at the drawing with care, and said,—
"Still, there are not in this drawing instruments or apparatus, or machines such as I have seen in my brother's books."
"But," answered Monsieur Roger, smiling, "it is not necessary that you should see instruments and apparatus and machines, as you say, to be in the presence of physical phenomena; and I assure you, my dear child, that this drawing which is under our eyes is connected with chemistry and physical science."
Miette now looked up at Monsieur Roger to see if he was not making fun of her. Monsieur Roger translated this dumb interrogation, and said,—
"Come, now! what does this drawing represent? Tell me yourself."
"Why, it represents two peasants,—a man and a woman,—who have returned home wet in the storm, and who are warming and drying themselves before the fire."
"It is, in fact, exactly that."
"Very well, sir?" asked Miette.
And in this concise answer she meant to say, "In all that, what do you see that is connected with chemistry or physical science?"
"Very well," continued Monsieur Roger; "do you see this light mist, this vapor, which is rising from the cloak that the peasant is drying before the fire?"
"Yes."
"Well, that is physical science," said Monsieur Roger.
"How do you mean?" asked Miette.
"I will explain in a moment. Let us continue to examine the picture. Do you see that a portion of the wood is reduced to ashes?"
"Yes."
"Do you also remark the flame and the smoke which are rising up the chimney?"
"Yes."
"That is chemistry."
"Ah!" said Miss Miette, at a loss for words.
Every one was listening to Monsieur Roger, some of them interested, the others amused. Miette glanced over at her friend Paul.
"What do you think of that?" she asked.
Paul did not care to reply. Albert wished to speak, but he stopped at a gesture from his father. Monsieur Dalize knew that the real interest of this scene lay with Monsieur Roger, the scientist, who was already loved by all this little world. Miette, as nobody else answered, returned to Monsieur Roger.
"But why," she asked, "is that physical science? Why is it chemistry?"
"Because it is physical science and chemistry," said Monsieur Roger, simply.
"Oh, but you have other reasons to give us!" said Madame Dalize, who understood what Monsieur Roger was thinking of.
"Yes," added Miette.
And even Paul, with unusual curiosity, nodded his head affirmatively.
"The reasons will be very long to explain, and would bore you," said Monsieur Dalize, certain that he would in this way provoke a protest.
The protest, in fact, came.
Monsieur Roger was obliged to speak.
"Well," said he, still addressing himself to Miss Miette, "this drawing is concerned with physical science, because the peasant, in placing his cloak before the heat of the fire, causes the phenomenon of evaporation to take place. The vapor which escapes from the damp cloth is water, is nothing but water, and will always be water under a different form. It is water modified, and modified for a moment, because this vapor, coming against the cold wall or other cold objects, will condense. That is to say, it will become again liquid water,—water similar to that which it was a moment ago; and that is a physical phenomenon,—for physical science aims to study the modifications which alter the form, the color, the appearance of bodies, but only their temporary modifications, which leave intact all the properties of bodies. Our drawing is concerned with chemistry, because the piece of wood which burns disappears, leaving in its place cinders in the hearth and gases which escape through the chimney. Here there is a complete modification, an absolute change of the piece of wood. Do what you will, you would be unable, by collecting together the cinders and gases, to put together again the log of wood which has been burned; and that is a chemical phenomenon,—for the aim of chemistry is to study the durable and permanent modifications, after which bodies retain none of their original properties. Another example may make more easy this distinction between physical science
