demanding more power. Considering the heavy work they had to do and the high cost of horses, manufacturers had a wide latitude in the matter of price. The western farmer wanted service and was willing to pay and pay well. That is why in the early history of the tractor manufacturers devoted their energies to the development of the heavy outfit.

As the new countries filled up and the land became broken, the necessity for big machines declined and the demand also declined. There is still a considerable market for the large tractor and it will continue for many years to come, but

And, just as in the case of the heavy tractors, it is not a problem of providing a machine and creating a demand but of supplying a demand. which economic conditions have forced upon agriculture. The problem facing the manufacturer is to satisfactorily meet existing conditions. The market is made ready to his hand if he can meet its exacting requirements.

A brief survey of the economic conditions which underlie the situation is both interesting and illuminating. They may be grouped under four principal headings:

1. The high initial cost and high maintenance cost of work animals.

2. The necessity for better tillage methods. 3. The increasing cost of human labor.

4. The necessity for a larger farm unit for most economic production.

GRAY TRACTOR CO., MINNEAPOLIS, MINN.

There are approximately twenty-four million work animals in the United States and about twenty-one million available for farm work. The average value of these animals, according to the last census, is $109.33. This estimate of value includes the small range horses, colts and scrub animals. Every farmer knows that the cost of a good draft horse is much higher, ranging from $140 to $200. The annual maintenance cost as determined by the writer last year for the entire country is $118.20. In some sections of the country it is less, in other sections considerably more. This estimate includes food, shelter, veterinary attendance and general care, but does not include the losses due to death or accidents.

A horse can not work at full capacity more than eight or ten hours a day and then only in favorable weather. In the hot summer months

THE WARD TRACTOR CO., LINCOLN, NEB. there is a considerable period during which horses can not be put at heavy labor. Added to the general maintenance cost of horses there is the cost of harnesses which must be added to the initial investment and entail a further charge for

maintenance. Horse labor is thus seen to be very expensive per unit. Not only that but each farmer is obliged, depending upon his type of farming, to maintain a certain number of extra animals to enable him to get through his work during the rush season of plowing, planting and harvesting. The extra animal equipment to meet peak load requirements is particularly expensive and can not be overcome even with the most carefully devised system of non- overlapping crops.

The necessity for better tillage methods is one that has been preached by every state experiment station and by the United States Department of Agriculture for the last dozen years. It is just as important as good seed or soil fertility. In fact, the three are a trinity that must stand together or our whole agricultural system will fall. Good seed and soil fertility have perhaps been preached louder than tillage but farmers are coming more and more to realize that good tillage is important.

Almost every agronomist will tell you that in

general we should plow deeper. A canvass of all the state agronomists made by the writer last year indicates that the depth of plowing, except in a few favored sections, should be doubled. According to the best statistics available it would require the expenditure of seventy per cent more power or, what amounts to the same thing, an increase of seventy per cent more time to increase the average depth of plowing one hundred per cent. Adding seventy per cent more work animals to the present number would be almost ruinous because even now it requires between twenty and twenty-five per cent of the products of the soil to support what work animals we are now using.

Increasing the time of plowing seventy per cent would be even more ruinous, for agronomists tell us good crops largely depend upon seasonable plowing and preparation of the seed bed. If plowing is done at the right time and to the right depth the soil will hold the moisture better. The experiments carried out at the Kansas Experiment
