Thirty-two of the thirty-four did not know what that meant. The meaning of the line, "For I have flung thee pearls and find thee swine," was utterly obscure to twenty-two of the thirty-four. One of them said it was a reference to "good opportunities given but not improved." Another said it was equivalent to the counsel "not to expect to find gold in a hay-stack." Even the line, "A Jonah's gourd Up in one night, and due to sudden sun," was utterly baffling to twenty-eight of the thirty-four. One of them spoke of it as an "allusion to the uncertainty of the length of life." Another thought it was a reference to "the occasion of Jonah's being preserved by the whale." Another counted it "an allusion to the emesis of Jonah by the whale." Another considered it a reference to "the swallowing of Jonah by a whale," and yet another considered that it referred to "things grand, but not worthy of worship because they are perishable." It is amazing to read that in response to Tennyson's lines, "Follow Light and do the Right--for man can half control his doom-- Till you find the deathless Angel seated in the vacant tomb," only sixteen were able to give an explanation of its meaning! The lines from the "Holy Grail" were equally baffling: "Perhaps like Him of Cana in Holy Writ, Our Arthur kept his best until the last." Twenty-four of these thirty-four young men could not recall what that meant. One said that the keeping of the best wine until the last meant "waiting till the last moment to be baptized!" All that may be solely the fault of these young men. Professor Lounsbury once said that his experience in the class-room had taught him the infinite capacity of the human mind to withstand the introduction of knowledge. Very likely earnest effort had been made to teach these young men the Bible; but it is manifest that they had successfully resisted the efforts. If Tennyson were the only poet who could not be understood without knowledge of the Bible, it might not matter so much, but no one can read Browning nor Carlyle nor Macaulay nor Huxley with entire intelligence without knowledge of the greater facts and forces of Scripture. The value of the allusions can be shown by comparing them with those of mythology. No one can read most of Shelley with entire satisfaction without a knowledge of Greek mythology. That is one reason why Shelley has so much passed out of popularity. We do not know Greek mythology, and we have very largely lost Shelley from our literary possession. The chief power of these other great writers will go from us when our knowledge of the Scripture goes.
