"Goto the ant thou sluggard; consider her ways and be wise," was a very good admonition in its time, but it was good for others as well as the sluggard. Indeed it is doubtful whether the wise man who recommended this remedy for laziness knew a hundredth part about the ant that he might have known had he lived in these days, and had Dr. McCook for a teacher. It has the merit of not being"spun out" in the text, and it is fully illustrated by plates taken from photographs. We have given the title in full, as the many free lectures on ants and spiders which Dr. McCook has given the public, deserves all the encouragement those who love intelligence can give. An interesting fact developed by Dr. McCook that we knew not of before, is that the"carpenter ant" does not confine itself to dead wood in its house-building operations, but takes to living trees; and there are many cases in which borers or some other "worms "have the odium of injuring trees which really should be laid at the door of these industrious but often annoying little creatures.
