in Plate IV, figure 1, is the simplest, least expensive, and most serv- 
iceable. More complete description is given elsewhere. 2 The method 
is adapted to all forage crops grown in Hawaii and is recommended 
to farmers for trial. 
This truck can be built by any farm blacksmith in two or three 
days at a total cost not exceeding $30. The bed of the illustrated 
truck is 12 feet long and 7 feet wide, and holds from three-fourths 
to one and a quarter tons of cured pigeon pea hay, depending upon 
the skill of the loaders. The truck body is supported by two 20-inch 
iron wheels, which have 4-inch tires and run on an axle placed about 
4 feet from the rear end of the V-shaped frame shown as A. A 2-inch 
reinforced pipe makes an excellent axle. When the loaded truck

is at rest, as when left in the field for the hay to cure, or when it is 
being loaded, or baled from, the front end is supported at the point 
of the V by a prop to keep the truck level. This prop is hinged so 
that it swings easily backward when the truck is being hauled. 
The standards at each end run to a point at the top, where a notch 
is cut to receive a 2 by 4 inch ridgepole that supports the canvas 
when used as a protection from rain. The floor of the truck is 
made up of seven 2 by 4 inch scantlings, 12 feet long and evenly 
spaced to allow the air to circulate freely from the bottom. A 
coupling device is fastened to each end of the truck. The front 
running gear of a low-wheeled wagon, furnished with a pole and 
doubletrees for two horses, is coupled to the front of the truck and 
a U. S. Dept. Agr., Farmers' Bui. 956 (1918).
