For awhile _Memory_ was crowded to its utmost extent, to the injury of the scholar, and more memorizing became the hobby in most of our schools. After a while the physicians checked this, by telling us that by crowding the memory we were developing a new disease amongst children, viz., Hydrocephalus, or water on the brain. Then our schools were in trouble, and resort was had to question-cards, and finally question-books became the hobby. In a few years question-books began to be stale and monotonous, and we appealed to the imagination and resorted to stories and anecdotes until they wearied, and then we searched commentaries, and theology was administered to the children in large doses. After that what was called spiritual teaching was adopted, but that soon degenerated into mere exhortation. Now we find that we must comprehensively grasp and rightly use them all, and make a hobby of none. The _memory_ is the grand store-house of the mind, and it should be well filled; but it is folly to over-stock it and overwhelm the brain. The _imagination_ is God's grand medium of worship and communion with him and the spiritual world. We cannot worship God without it. Let us not exorcise it because some abuse it. "The _imagination_ has the same place in the faculties that the eye has among the senses." The _intellect_ is God's great gift which distinguishes man from the brute. Let us never worship nor pervert it. The _heart_ is the soul of man. To save it the Son of man came down from heaven to earth. Unless the heart is gained all is lost; but if we appeal to the heart alone, we but develop the puny Christian. Let us, therefore, use all wisely, but misuse none. At first the aim of Sabbath-school teaching was very feeble and indefinite: to keep the children out of mischief--teach them to read the Bible--correct their manners and make them good children--not profane and disobedient. Then the aim was to give them a general knowledge of Bible history and catechism. The ablest early Sabbath-school works published under the patronage of the Queen of England did not even hint at the possible conversion of the children. The Bible was long introduced as a book of task lessons to the young, and catechism and hymn learning engrossed our Bible classes. Now, the Bible is exalted, and so applied in our Sabbath-schools as to be the most attractive of all books to the children and youth. _Now_, the aim of Sabbath-school teaching is, or ought to be, the _immediate_ conversion of the children to Christ. It is a poor excuse to suffer a child to drown because we have but one opportunity of saving it. _Now_, many Sabbath-school teachers have learned the great and precious art of leading even little children to Jesus--"Just now."
