- Editor's Notes
- Too busy since return from Switzerland to ans your letter. Sprague's tests were not made for us, but from critical point of view. Can see what is fairly the capy of hte machine. Old "L" had one strand to carry 150 lights; the [?] machine had 8 strands to carry 200 light if wires closely packed, or more if not closely packed. New "H" has 14 strands for 500 lights; at this rate the new Sprague machine would run 281 light or more if not so tightly packed. But since Sprague was here we've improved about 30% and aren't quite done yet.
