It is known that the night watch on several oc-casions has slept and left the turbine to take care of itself. Be-sides, the accidents that occur are of no moment compared withsimilar cases of the engine. The large gain in the use of the tur-bine completely warrants the occasional service of a competent in-spector or attendant. It mav be correctly stated that turbines came as a matterof necessitv for the large size units. However, they are growingm importance in small sizes as well. In the latter case, the com-mercial conditions are different, involving lower efficiency andcost. Nevertheless, these are necessarily in competition with thesmall engines and must compare favorably or excel them in ef-ficiency. These are the factors that underlie small turl)ine work, andthe design conforming to the requirement is shown in Fig. turbine is of the re-entry type, employing two velocitydrops.
