This bulletin discusses gas tractors with regard to their operation and maintenance in relation to farming practices in the eastern United States, particularly in New York. "Tractors using gasoline or kerosene are increasing in numbers on eastern farms. More than 250 New York State farmers furnished detailed reports of their experience with tractors during 1917 and the spring of 1918, and on these the information given in this bulletin is based." -- p. 2

Revised edition. "The wheat jointworm is a very small grub which lives in stems of wheat, sucking the juices of the plant and causing a swelling in the stem. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks no other kind of plant. The injury which it does to wheat is very distinct from that caused by the Hessian fly, yet the depredations of these two insects are often confused by farmers. This paper is intended, therefore, to give a brief outline of the life history and the nature of the injury to the plant by the jointworm so that any farmer may readily recognize its work and be able to apply the measures of control herein recommended." -- p. 3-4
