Note. — The power required for all machines varies greatly with the 

 make: the manufacturers' catalogues usually give the power they recommend 

 ani one should be largely guided by these, remembering that the manufac- 

 turers place the power requirements as low as possible and that it is better to 

 have a little too much than not enough power.
