 involving a delay of 15 to 20 minutes in starting up, but it still 

 remains an exceedingly useful motor for small powers.

IVevious to the invention nf the power gas ])roducer, bv 

 Dowson, successfully applied in iSSi. ilie gas engine 

 was dependent upon town's gas. and was making little 

 progress. The production of a cheap gas of low calorific 

 value, in a practically automatic ap])aratus. having a thermal 

 efficiency higher than the l)est boiler using coal, for use in a gas 

 engine having a thermal efllcienc)- at least 10 ])er cent, higher 

 than that of the best steam engine, was bound in time to make 

 its inrtuencc felt in spit*.' of tlie o])position of iireitidiccfl steam
