Caldwell Island, ON
Centrex & Tropic

Mr. & Mrs. Caldwell have the earliest known North American produced Sun-Mar (a Tropic) in continuous operation on their island in the St. Lawrence River between Canada and the US.

The Caldwells shown here in front of their cottage in a picture taken some years ago, upgraded to a Centrex and put their old Tropic into their children's cottage on the island.

Eleanor, their granddaughter, and the third generation of composters, is shown posing with the raised and very colorful toilet installation for the new Caldwell Centrex.

Meanwhile Mr. Caldwell is showing his tomato plants which he feeds with compost extracted each spring from the Tropic. The Caldwells use their toilet continuously from early spring to late fall, "when I get frozen out" says Mr. Caldwell.
