CHALK.
1. Like slate, chalk comes out of the hills. It is white and soft. It is used for many purposes. The farmer puts it on the fields sometimes, to make the soil better. It holds water and keeps the soil moist.
2. We get lime and whiting from chalk. We use it in these forms for making our ceilings and walls clean. It is used, too, for writing on the blackboard. Chalk is found in many parts of England. Kent and Hampshire have most. Chalk-pits are often seen in the hills.
3. Chalk is formed of thousands of tiny shells.
