1. Some sprigs of ivy had been standing all the winter in a vase. The
water had often been changed, and the leaves washed.
2. When spring came each spray began to put out buds. The buds were not
all at the ends of the sprays, but came out also close to the old
leaves.
3. At last there was a very small bud between every old leaf and the
stem. When the first bud opened into a leaf, Dora and Harry clapped
their hands, and called every one to look.
4. 'How clean and sweet it is!' cried Dora. 'And do you see something
like wool or hair on it?'
'How curly it is!' said Harry. 'It is not quite open yet. Why, it is
like a hand! All the leaves look rather like hands, don't they? See;
one, two, three, four, five!'
5. 'Look at this old leaf against the light,' said the mother; 'now you
can see the five long fingers. But people call them ribs, not fingers!
They are for the purpose of keeping the leaf spread out.'
6. 'Like the ribs of an umbrella,' said Harry. 'They seem very strong;
the middle one, which goes up straight from the stem, is the strongest
of all.'
[Illustration: Spray of Ivy.]
7. Dora was holding up one spray after another to the light. 'What are
all these pretty marks on the leaves, mother, lines crossing about all
ways?'
'Those are veins, dear. They carry the sap that feeds the leaves.'
8. 'What is sap?'
'The blood of plants and trees.'
'Oh,' said Dora, 'then that is the wet that comes out when I pick a
flower or cut a leaf!
9. 'But look at this!' and she held up one of the sprays.
At the end of it was a little bunch of white, curly roots. Each root was
not much thicker than a thread.
10. 'Don't touch them,' said the mother; 'roots are very tender things.'
'What is the good of them?' asked Dora.
'What is your mouth useful for?' asked her mother.
11. 'Oh, do you mean that the ivy eats and drinks?'
'Yes, that is what I mean. These roots take out of the water, or out of
the earth, all sorts of things good for the food of the plant. They then
send them up into the stem and on into the leaves.'
12. 'Mother,' said Harry, 'let us go and plant all this ivy. I am sure
it wants to try the taste of the earth!'

1. 'Let us go over to that log where we sat when we saw the rabbits,'
said Dora to Harry.
2. 'All right! We can play at ship, and the grass shall be the sea.'
'Or we can have see-saw, if we can find some wood to lay across the
log.'
3. They were soon at the log, and on it they sat down, and looked about
them.
The log was the trunk of an old oak, and a little way off stood the
stump, with many new shoots and leaves coming out all round it.
4. Dora went and stood on it, and called out that she was on a hill. She
jumped off and on a few times, and then said it would make a good table,
and they might have tea on it.
