o'clock
How many of our country boys enter the freshman class of college in robust health , which lasts them about a twelvemonth ; then in the sophomore they lose their liver ; in the junior they lose their stomach ; in the senior they lose their back bone ; graduating skeletons , more fit for an anatomical museum than the bar or pulpit . `` Midnight oil , '' so much eulogized , is the poorest kind of kerosene . Where hard study kills one student , bad habits kill a hundred . Kirk White , while at Cambridge , wrote beautiful hymns ; but if he had gone to bed at ten o'clock that night instead of three o'clock the next morning , he would have been of more service to the world and a healthier example to all collegians . Much of the learning of the day is morbid , and much of the religion bilious . We want , first of all , a clean heart , and next a strong stomach . Falling from grace is often chargeable to derangement of gastric juices .
