1905-6. ] MINIATURE STEAM ENGINES, 277 
examine as best you can the smallest engine on earth, and see it demon- 
strated by high speed that the principles which actuate the steam engine 
as a pressure machine still hold good even in this small sized and speedy 
machine. 
Sometimes I am asked by the practical ones, ‘‘Why did you make 
them?’’ ‘‘What use can they be put to?’’ Well, it has been a pleasure 
to make them, and they have given pleasure to hundreds who have visited 
the shop and who can appreciate small and accurate work. Their pri- 
cipal use, I fancy, is in the building line—reputation building—and so 
far they have done good work. 
NotE—Both engines were then exhibited running at high speed, 
and were examined by aid of magnifying glasses.
