introducing it by means of an injector. These different methods ordinarily work very
well in practice, but we have occasionally had complaints to the effect that the soda ash,
when passed through the pump, eats out the packing thereof. We think this would
hardly be likely to occur with a new packing, but with an old one, which had become
impregnated with oil or grease, the soda ash might easily give some such trouble as has
been reported.
