WHEN first you strive a faithful Friend to find,
Explore the secret Motives of his Mind;
Nor, rashly credulous, his Friendship trust,
Before you know, what Passion rules him most:
But, as a Horseman checks the Courser's Speed,
Till he has try'd the Temper of his Steed;
So check the Reins of Friendship, till you prove,
What sways the Person, Interest, or Love.
