called mill-stones, which are turned round, and by which the corn is bruised into flour. You have all seen flour, and you know how useful it is. Bread is made of flour. To make bread, the flour is mixed with yeast, which turns it all into paste, which is called dough: the dough is divided into pieces, and shaped into loaves, which are baked in the oven; and then we have bread, which we know to be very good, and without which we should hardly be able to live. And, now, can you tell me how the corn grows? The farmer makes the ground ready, and sows the seed; but he can do nothing more. Who makes it spring up above the ground, and causes the ear to shoot, and fills it with grains of corn, that it may be our food? It is God who does all this. He makes His sun to shine, that it may be warm; and sends His rain to water it. We must, therefore, thank him for the bread we eat, and pray to Him to send us good weather, that we may have abundance. There is another lesson which we may learn from this subject, Do you remember what St. Paul says about corn being sown in the earth? He tells us that one little grain is cast into the ground, and a whole plant springs up, with its blade, and ear which has a great many grains. And what is this like? It is like the body when it is laid in the grave, which dies and moulders away; and yet it will rise again, as the green corn springs up; and it will be much more glorious and beautiful than it ever was before. But when will the body rise again? On the morning of the resurrection, when Christ shall come, and all his people shall meet him with joy and gladness. be with him, and like him for ever. They shall If you wish to be happy on that glorious day, you must think about it now. All men will not be happy then, but only those who are the children of God. Their sins are washed away by the blood of Christ, and their hearts are made pure and holy by God's spirit. Pray that your sins may be washed away, and ask God to make your hearts holy and like the Saviour. WHAT is flour made of? How is the ground made ready for sowing corn? What is the plough used instead of? How is corn sown? What is young corn like? What is the colour of ripe ears of corn? Who cuts corn? What is corn cut with? How is corn kept? How is it separated from the chaff? What is done next? What is ground corn called? What is mixed with flour to make bread ? What is bread called before it is baked? Who makes the corn to grow? For what should we thank God? What may corn sown in the ground remind us of? When will the body rise again? Who will come on the day of the resurrection? Who only ? How can sin be washed away? Who will make the heart holy? What must you do to get these great blessings? GLASS. Do you know what glass is made of? The commonest kind of glass is made of soda and sand; but to make finer sorts of glass, flint beaten into powder is used instead of sand. The proper quantities for making glass are mixed together, and then put into a very hot furnace, where they remain a long time, till they become united together, and bright and clean. It is then glass; but it is red-hot, and very soft. In order to make the glass into shapes, as bottles and drinking glasses, it is taken out of the furnace in small lumps at the end of a long pipe, through which the glass-blower blows, and thus brings it into shape. It is rather difficult to imagine how this can be done without seeing it; and, no doubt, it requires great care and skill in the workmen. : There is another very important use of glass besides that of making bottles and other vessels. Glass is generally used for windows; and it is so valuable for this purpose that we cannot imagine a comfortable house without it. The glass used for windows is of two kinds, plate and crown glass the former is the most clear and beautiful; but it is very expensive, and not so commonly used as crown glass. It is made by pouring the melted glass upon large tables, and then rolling it to the proper degree of thickness by heavy rollers. The great difficulty in this process, is to make the plates of the same thickness throughout, and not thinner at one part than at another. Crown glass is made with a blow-pipe, in the same way as bottles. The glass is blown into a large ball, and then cut open before it is cool, and turned very quickly round and round: this makes it spread out quite flat and round. There is a rough knob in the middle, where the glass stuck to the pipe. The piece of glass with the knob is put into very common windows. It is said that the persons who first found out how to make glass were sailors. They made a fire on the sand by the sea-shore, of dry seaweeds. Soda is generally got from sea-weed. The soda in the sea-weed and the sand were melted together by the heat of the fire, and made a common sort of glass. This happened a great many hundred years ago. Perhaps you think I have forgotten to tell you how looking-glasses are made. They are made of plate glass, which is the best and clearest kind: a thin layer of quicksilver is put behind the glass, after which, instead of seeing through as we did before, we see a picture of everything in front of the glass. Looking-glasses are very useful; but some people make a bad use of them, and are much too fond of looking at themselves, and thinking about their dress and appearance. Such people ought to remember, that their bodies must soon die, and that it is of more use to look at their souls. But how can they do that? The Bible is like a lookingglass for our souls, for it tells us both what we are, and what we ought to be. Or what is common glass made? In what state is glass when it comes out of the furnace? How is it made into bottles and glasses? Besides bottles and wine glasses what is made of glass? How is plate glass made? And how crown glass? Who are said to have first discovered how to make glass? Of what sort of glass are looking-glasses made? What may be called the looking-glass to the soul? RAIN, SNOW, AND HAIL. WE have often seen the rain; but we may do this without knowing why it falls, or how it is formed. It is not right to live in the world which God has made, without paying any attention to the wonderful works which surround us. They teach us his power, wisdom, and goodness. We ought, therefore, to examine them carefully, and be glad to learn as much of their nature as we are able. Would you like to learn something about rain? Where does rain come from? I suppose you will say that it comes from the clouds. True; but how is there water in the clouds? how does it get there? And how is it that all the rain is not down, since it has rained so often every year since the beginning of the world? Well, let us begin from the beginning. The water which forms rain, comes from the sea. It rises up in the air by what is called evaporation. Evaporation means turning to vapour or |
