Tandem carts or gigs are made with straight or very slightly bent shafts, which should hang nearly level when harnessed, although a trifling inclination towards the tail is admissible. A cart should never hang "by the head."
It will readily be seen by these suggestions that the height of the cart is a very considerable factor in the selection of the wheeler. The arrangement and buckling of the tugs is a most important point, for on this the ease of motion of the cart depends in a very great measure. When the shafts are level and the buckles dropped or raised to suit this condition, the tug bellyband is buckled loosely ; it should have plenty of freedom to allow of an upward and downward play of the shafts when the cart is driven over an uneven surface.

A harness which is thoroughly tandem is shown in Plate XXXIV, but there has been a tendency of late
