On attempting to diminish such loss an inferior product would be obtained, anq in the subsequent chemical steps of my process less good paste would he obtqinerl. Practicgllv good results will be obtained by losingfiiboutone'quartcr of the weight of the stems. Only after this first mechanical step of my process the paste is ado-phi to undergo the chemical treat ment. The water will be drained from the .cylinder Whereonly the paste is left.
