has become of the water you put into the kettle ? Did it come out of the 

 spout as steam or vapor? If so, where is it? Let us see. Put a httle 

 more water into the kettle, and get your plate or glass that you put 

 outside to get cold. When the vapor begins again to come out of the 

 spout, hold the glass in the cloud a little distance from the spout. Very 

 soon you will see that the glass is wet, and in a short time water will run 

 down the side next to the kettle and drop off. What does this show? 

 If the weather is cold out of doors, you may see the window panes be- 

 come cloudy, and if you have boiled away a pint or more of water, you 

 may see the little streams of water running down the window panes. 



You cannot see any steam or vapor near the windows nor in the air 

 of the room except near the spout of the tea-kettle, but you may be sure 

 that all the water you put into the kettle is now in the air of the room. 

 You have taken some of the water out of the air with your cold plate, 

 and some has been taken out by the cold window panes. If you could 

 find some way to cool the air of the room suddenly and catch the water 

 as it comes from the air, you would get back every drop of the water 

 you i)ut into the kettle. What change did the heat from the fire make 

 in the water? What change did the cold glass or the cold window pane 

 make in the vapor in the air? 



It is not necessary to boil the water to make the change take place. 

 Boiling only makes it change faster. When your mother hangs the 

 clothes out on the line even on a cold day, they soon become dry. The 

 heat from the sun is quite enough to cause the water in the clothes to 

 change to vapor and pass into the air. This change is going on all the 

 time from the surface of the ocean, the lakes, the rivers, and the moist 

 earth, and although you cannot see it, the air always contains more or 

 less water in the form of vapor. 



MEMORY SELECTIONS. 

 "Hear the woodpecker, rap-a-tap ! 

 See him in his cardinal's cap!" — Maurice Thompson. 



"The busy nuthatch climbs his tree. 



Around the great bole spirally, 



Peeping into wrinkles gray. 



Under ruffled lichens gay. 



Lazily piping one sharp note 



From his silver mailed throat." — Maurice Thompson. 



"The squirrel came running down a slanting bough, and as he stopped 

 twirling a nut, called out rather impudently, 'Look here! just get a 

 snug-fitting fur coat and a pair of fur gloves like mine and you may 

 laugh at a northeast storm.' " — 'J'horcau.
