BOURN

A limit or boundary; a word familiar to the Freemason in the Monitorial Instructions of the Fellow Craft's Degree, where he is directed to remember that we are traveling upon the level of time to that undiscovered country from whose bourn no traveler returns; and to the reader of Shakespeare, from whom the expression is borrowed, in the beautiful soliloquy of Hamlet:

Who would fardels bear;
To grunt and sweat under a wearly life ;
But that the dread of something after death
The undiscovered country, from whose bourn
No traveller returns-puzzles the will.Act III, Scene 1. Fardels here means burdens.
