Points out that correct manufacture of propellers according to design is most essential, since errors of workmanship may produce considerable losses in ultimate propeller efficiency; these errors are almost unavoidable in cast-iron and cast-steel screws, due to warping and shrinking; with bronze propellers, however, pitch can be worked to with tolerance as low as 1 per cent; for this and other obvious reasons bronze propeller, in spite of its greater initial expense, is becoming increasingly adopted; refers to workshop methods adopted by Ostermann and Flus, of Cologne, and by Zeise.
