Drummond's most important works are the "Cypresse Grove" and the poems. The "Cypresse Grove" exhibits great wealth of illustration, and an extraordinary command of musical English. It is an essay on the folly of the fear of death. "This globe of the earth," says he, "which seemeth huge to us, in respect of the universe, and compared with that wide pavilion of heaven; is less than little, of no sensible quantity, and but as a point." This is one of Drummond's favourite moods; and he uses constantly in his poems such phrases as "the All," "this great All." Even in such of his poems as may be called more distinctively Christian, this philosophic conception is at work.
