The Great Gatsby
The Great Gatsby, canvass
I'd like to know if "canvas" in the following excerpts from the chapter Three of The Great Gatsby refers to a kind of "tent":
1) Suddenly one of the gypsies in trembling opal seizes a cocktail out of the air, dumps it down for courage and, moving her hands like Frisco dances out alone on the canvas platform.
2) There was dancing now on the canvas in the garden, old men pushing young girls backward in eternal graceless circles
Thank you.
