Nineteen birds and one bird more,
Just make twenty, and that's a score.
To the score then add but one;
That will make just twenty-one.
Now add two, and you will see
You have made up twenty-three.
If you like these clever tricks.
Add three more-for twenty-six.
Then three more, if you have time;
Now you’ve got to twenty-nine.
Twenty-nine now quickly take—
Add one more and Thirty make.
