Here, then, we can picture the sturdy archers of Plantagenet days stretching themselves; their bows, not the toys of the modern toxophilite with their thirty or forty pounds of pull, but of twice the power (eighty lb. being a common pull in those times), and their "cloth-yard" arrows, over three feet long, whistling to a target not planted forty or fifty yards away, but twelve times the distance--the whole length of these butts. Indeed, for anything under two furlongs light arrows were not allowed, and the heavy regulation war arrow had to be used. Each man was taught, as Bishop Latimer tells us in recording his own youthful training, to draw his bow not by mere strength, but by sleight of hand, "to lay the weight of his body into the bow," and to draw the bowstring not to his breast, like other nations, but to his ear. Small wonder that with eye and sinews so trained our English archers became the wonder and the dread of Europe, or that their shafts decided so many a battlefield--Cressy, Poictiers, Agincourt, Flodden. A mile further we cross the Bourn Brook, a tiny tributary which joins the Cam near Grantchester, hard by a small station on the Cambridge branch of the London and North Western Railway, called Lord's Bridge, from the Lord Hardwicke who, in the beginning of the nineteenth century, substituted a bridge for the earlier ford here. To our right we see, across the fields, the church tower of Comberton; where, on the little village green, can still be seen the worn remains of a turf-built "maze," first traced out no one knows when, but certainly not later than the sixteenth century. Various mystical reasons are conjectured for the origin of these mazes, of which a fair number still exist in England (especially in the Eastern counties), while many more are known to have been destroyed by the Puritans of the seventeenth century as relics of heathen superstition. Such, indeed, they probably are. Mr. Walter Johnson, in his "Folk Memory," considers them to be exceedingly primitive, begun in connection with "ceremonial dances of painted heathen round a prehistoric camp fire." This Comberton maze is fifty feet in diameter, while the tracks are two feet in width, divided by slight banks of turf, once, it would seem, about a foot in height, but now much worn down. The next turn (to the left) leads to Harlton, a pretty, shady village, with a fine Perpendicular church, having a stone rood screen, which is rare, and, what is yet rarer, a still surviving stone reredos of the fifteenth century, with a central recess, once closed with a door, and evidently intended as a "Tabernacle" for the Reservation of the Blessed Sacrament. The six niches on either side of this recess were as evidently meant for images of the twelve Apostles.
