They've warned you, perhaps, against letting me pass,
I shan't soil your ceiling, I shan't spoil your pictures,
Or make nasty smells like that dirty imp, Gas!
You're prejudiced clearly, and that is a pity,
Why, bless you, I'm spreading all over the place!
My spark is pervading the whole of the City;
The dingy old Gas-flame must soon hide its face.
I'm brilliant, and clean, and delightfully larky;
Just look at my glow and examine my arc!
Fwizz! How's that for high, and for vivid and sparky!
