Originally printed in 1917 with Imprimatur.

In presenting this brochure on the Holy Sacrifice of the Mass, nothing original is claimed by the author. The matter culled from miscellaneous reading is condensed, simplified and arranged in a manner which may help teachers who have little or no leisure for such work. It is left to the individual judgement of the teacher to decide as to whether or not they should teach the children to memorize the various verses interpolating the study.
