TRACTORS AND HORSES IN THE WINTER WHEAT BELT. 
NUMBER OF WORK STOCK. 
The total number, weight, and value of work stock of different 
kinds owned at the time of the investigation on the farms operated 
with one tractor and horses are given in Table 8. The values of the 
work stock shown are the averages of the farmers’ estimates of their 
value at the time of the investigation (August and September, 1921).

The number of colts in comparison with the number of work stock 
on these farms is shown in Table 9. The number of “‘‘other” colts 
includes all young stock over 1 year of age which have not been 
broken to harness. Colts less than 1 year of age were found on only 
about one-third of the farms, and there was no young stock whatever 
on nearly half of the farms. For all farms there was 1 colt less than 
a year old for each 10.4 head of work stock and 1 ‘‘other” colt for 
each 4.5 head. This is considerably more than enough for replace- 
ment for the entire group of farms. 
In the southern area the ratio of the number of colts less than 1 
year of age to the total number of work stock was 1: 10.6; in the west- 
ern area |: 7.3; and in the northern area 1: 19.9.

The number of work stock kept depended to a certain extent upon 
the size of the farm. The average numbers on the farms of different 
sizes are shown in Table 10. There was considerable variation, 
however, in the number kept on farms of the same size in the same 
area. Many of the tractor owners were keeping more work stock
