At that point, simple faith came to Ernie's rescue: in the same bathroom, he had seen the green flame; it had burned his fingers.
Quickly he dipped up a little of the white powder on the edge of a fifty-cent piece, dumped it in the gas tank without quibbling as to quantity, rapped the coin on the edge of the opening, closed and pocketed the blue box, and picked up the spurting hose and jabbed it into the round hole.
His heart was pounding and his breath was coming fast. That had taken real effort. So he was slow in hearing the footsteps behind him.
His neighbor's gate was open and Mr. Jones stood open-mouthed a few feet behind him, all ready for his day's work as streetcar motorman and wearing the dark blue uniform that always made him look for a moment unpleasantly like a policeman.
Ernie swung the hose around, flipping his thumb over the end to make a spray, and nonchalantly began to water the little rectangle of lawn between sidewalk and curb.
The first things he watered were the bottoms of Mr. Jones's pants legs.
Mr. Jones voiced no complaint. He backed off several steps, stared intently at Ernie, rather palely, it seemed to the latter. Then he turned and made off for the streetcar tracks at a very fast shuffle, shaking his feet a little now and then and glancing back several times over his shoulder without slowing down.
Ernie felt light-headed. He decided there was enough water in the gas tank, capped it, and momentarily continued to water the lawn.
"Ernie! Come on in and have breakfast!"
He heeded his sister's call, telling himself it would be a good idea "to give the stuff time to mix" before testing the engine.
