When every strap a buckle found

When every strap a buckle found, And every part was safe and sound, Then 'round the cart the Brownies flew,— The hardest task was yet to do. It often puzzles bearded men, Though o'er and o'er performed again.

Some held the shafts to steer them straight, More did their best to balance weight, While others showed both strength and art In backing Mag into the cart. At length the heavy job was done, And horse and cart moved off as one.
