[" I got a BfCfjnd-hand sewing-machine table . . . Then I took another

 On the top of the first table I put a piece of pine board I in. thick. Into 

 this I put three small cantors ujiside down. I bored three holes in the

 No. 2 over top No. 1 , bo that the castors camo over the surface about 1/4 in.
