 Potatoes in the Three Bins 



x\nother test using injured and uninjured tubers stored in crates while 

 m storage so that there was free circulation of air around each crate was 

 conducted. The uninjured potatoes lost 3.08 per cent of their weight 

 and the injured lot lost 5.68 per cent during eight and one-half months 

 of storage.

The Homemade Power Wood Saw 



Stimulated by the interest in fuelw ood resulting from the threatened 

 shortages of oil and coal for heating purposes, the Director designed and 

 constructed a wooden frame by means of w hich a small electric motor 

 or a gasoline engine of fractional horsepower weighing less than 50 pounds 

 could be attached to a one-man crosscut saw. Presumabl\', this equipment 

 is adapted to cutting large logs in the woods in preparation for fireplace 

 or furnace. Some 10 cords of wood comprising, maple, oak and elm from 

 6 inches to 3 feet in diameter were sawed in two-and four-foot lengths. 

 The whole apparatus is mounted on a sled. Where the snow is not too 

 deep it can be rather easily hauled to ne\\' positions by one or two men. 

 It was loaded in a light trailer behind a touring car for Saturday afternoon 

 trips to the woodlot. After a little more perfecting, some descriptions 

 and illustrations may be made available in mimeographed form.

Buck Rake Construction and Use on New Hampshire Farms 



According to the county Farm Bureau agents, the current labor situa- 

 tion has caused many requests concerning the "buck or transport rake" 

 as a time and labor saver. The construction and use of this type of haying 

 implement is being experimented with at the university farm. 



Because of its relativel}' long wheel base and heavy engine necessary 

 for counterbalancing the weight of the loaded rake at the rear, a 1931 

 Buick sedan \\ as selected for the power unit. The rake itself was con- 

 structed according to the Ohio plan \\'ith a few adaptations made neces- 

 sary by available materials and l)\' the frame construction of the pow er 

 unit. The rake was attached to the power unit by construction of a 

 hinge, using a ^-inch pin. 



A power-driven hoist was contrived b\' making use of an automo- 

 bile starter, a fly wheel, a transmission, and a winding drum made from a 

 piece of 3-inch pipe. In the field trials that have been made this hoist will
