But we brought with us a frozen thing which is called ... _Children_.--Snow. What is it the stove gives us? _Do you remember?_ [4] _Children_.--Heat. I want Maria to tell me. And now, Peppino. [Footnote 4: The children are expected to know that the stove gives out heat, by an effort of _memory_.] Do you know, our mouths also give out heat. Open yours. Not too much! Hold up one hand in front of it, the right hand. Breathe on it as I am doing. Let us breathe again; now let us send our breath outwards, as I am doing. Again ... again ... again. That's right. Now feel. You see your mouth too gives out a little ... _Children_.--Heat. Now let us try putting a little snow into it. A little piece like this. Oh! the heat of the mouth is escaping, it has already gone at the icy touch of the snow. _Children_.--Our mouths are cold now. Yes, that's right. They are very, very cold, so cold that they are what we call ... _Children_.--Freezing. Perhaps Giuseppe doesn't know. He didn't say it with the others. Say it again, that he may say it with you. Again. That will do. Bravo, Giuseppe. So our mouths were ... _Children_.--Freezing. Let us eat another little piece of snow. The snow turns to water in our mouths, because it is made of water only. Now bread is made of water too, but not _only_ of water. What does the baker want to make the dough for bread?... _Children_.--Flour. And what else? _Children_.--Salt. And what else? _Children_.--Yeast. I see Luigi is still eating snow, and Alfonso too, and Pierino. Do you like it? _Children_.--Yes, Signora. Do you like it? _Children_.--Yes, Signora. Me too, me too (correct). Well, eat a little more, but not much, it might make you ill. It is so freezing (I repeat this word very often, because it expresses the idea I am trying to convey). When it snows it is so very cold, and just think that there are many children, many people, who are not warmly dressed and have no stoves; they are very poor. They suffer very much, and some of them die; poor people! How fortunate we are, on the other hand! We have so many garments (they have learned this word) to cover ourselves with; we have a stove at home and one at school, to warm us. How lucky we are! _A child_.--I have no stove at home. I know you have not, Emilio, and I am very sorry. Children, you must be kind to Emilio and Giuseppina, because they are very ... _Children_.--Poor. Have you eaten it all? _Children_.--No, Signora. Now let us go into the courtyard and throw away the rest of the snow. Then we will put the boxes on this table to dry. And to-morrow I will show you a pretty picture of country covered with snow. Come along; bring your boxes, and when you have emptied them put them back where I told you." I intend to repeat this lesson in another form, combining others with it, and referring in it to other ideas, which bear a relation to that here set forth.
