INTERPRETATION OF THE TABLES AND CHARTS. 
As stated in the beginning, the figures in the tables and charts can 
not be anything more than fair averages, just as rainfall data by j 
months are fair averages. Common sense and judgment must be 
used to make the tables apply to a particular farm. 
The farm to which one might wish to apply the data may not be 1 
in the county where the figures were gathered, but a fanner can use j 
the data from the county that is nearest to him and make such modi- 
fications for latitude, longitude, or average rainfall as may seem 
reasonable. A difference of 100 miles makes little difference in itself. 
ALLOWANCE FOR SOIL. 
Most of these data are for sandy or sandy loam soils. If they are 
to be applied to silt, clay or so-called "buckshot " soils, 10 to 40 per 
cent should be added for the work of preparation. 
WEATHER. 
Very dry weather, by making soils dry and hard, makes them 
difficult to break and prepare and everyone must use his own judg- 
ment as to how much to allow for this factor. 
If the weather is wet in the spring when the ground should be pre- 
pared, it will shift the work to a later date. If it is very wet after 
row crops are planted grass and weeds grow more rapidly, which 
adds to the work of both cultivation and hoeing, especially to the 
hoeing. No rule can measure the amount of such increase. Every 
one must use his own judgment in regard to it. Ram at such a time 
will also shift some of the work from the normal time to a later time. 
Wet weather during the haying and harvest of small grain increases 
the amount of work because the hay and gram may have to be 
handled an extra time, and it certainly delays the work to some 
extent. During cotton picking or the harvest of other crops wet 
weather delays the work even if it does not involve an extra hand- 
ling. It is likely also to lengthen the time of work by decreasing 
the work accomplished in a day. 
In harvesting corn and other crops a storm may so beat them 
down that more work is involved. 
Work that is performed in the winter months is shifted according 
to the winter weather. In January of some years a farmer can plow 
22 days out of the month and in other years no plowing at all can 
be done. In the former case, much plowing is done, hence the work 
is shifted from the normal date to an earlier date. In the latter 
case, it is shifted to a later date. All such contingencies must be 
kept in mind. 
WEEDINESS OF LAND. 
Some fields are much more foul than others with weeds and grasses; 
this makes a difference in the amount of hoework required on row 
crops and it may also affect some other operations. The difference 
between the amount of hoeing on cotton in Columbia and Pulaski 
Counties is partly but not entirely due to differences in weediness of 
land. Nut grass, Bermuda grass, and Johnson grass land involve 
much extra work.
