The Sabbath-school may be said to be divided into three courses, namely, the preparatory or infant-class, the collegiate or Sabbath-school proper, and the post-graduate or Mr. Parker's Bible-class. What can a mere babe of three or four years learn in Sabbath-school? sneers the critic. Not much, I grant you, of justification by Faith, or Effectual Calling; but certain elementary precepts can be impressed upon the mind while it is still in a plastic condition that never can be wholly obliterated, come what may in after life. Prime among these elementary precepts is this: “Always bring a penny.” Some one has said, “Give me the first seven years of a child's life and I care not who has the remainder.” I cannot endorse this without reserve; but I maintain as a demonstrated fact: “Bring up a child to contribute a copper cent, and when he is old he will not depart from it.” It was recently my high privilege to attend a summer gathering of representative religious people in the largest auditorium in this country. Sometimes under that far-spreading roof ten thousand souls were assembled and met together. This fact could be guessed at with tolerable accuracy from the known seating capacity, but the interesting thing was that it could be predicated with mathematical certainty that exactly ten thousand people were present, because the offertory footed up exactly one hundred dollars. What an encouragement to these faithful infant-class teachers that have labored unremittingly, instant in season and out of season, saying over and over again with infinite patience, “Always bring a penny,” to know that their labor has not been in vain, and that as a people we have made it the rule of our lives always to bring a penny--and no more. I have often tried to think what a Sabbath-school must be like in California, where they have no pennies. It seems hardly possible that the institution can exist under such a patent disability, and yet it does. Do they work it on the same principle as the post-office in that far-off land where you 'cannot buy one postal card because the postmaster cannot make change, but must buy five postal cards or two two-cent stamps and a postal? In other words, does a nickel, the smallest extant coin, serve for five persons for one Sunday or one person for five Sundays? I have often wondered about this.
