New York AGRICULTURAL EXPERIMENT STation. 147 
This table shows that there is a gain in yield of the spraved 
over the unsprayed rows in every case. The total gain on two- 
fifths acre is 283 lbs., or at the rate of 707.5 lbs. per acre, an 
increase of 47.8 per ct. 
Asa record of the prime and cull bunches from the treated and 
untreated rows was kept and the value of the bunches known, the 
_ results can be compared in values and bunches as well as in total 
weights. Table V shows not only the total weights from sprayed 
and unsprayed rows, but also the total primes and culls from 
each, together with their values and their differences.

In general this table shows the same conditions throughout as 
Table II which shows results for 1899, though the differences are 
not as marked. When the results are compared on the same 
basis, namely, as percentages, it will be seen from Table II that 
the percentage of yield is less than the percentage of value,. while 
in Table V these conditions are reversed. Evidently this varia- 
tion results from the varying yields of primes and culls combined 
with the difference in price received for them. Hence the intro- 
duction of the bunches as a means of obtaining more accurate 
results, while furaishing a method of determining and comparing 
the values, at the same time introduces another factor of 
variation. pio ti 
Taking the results of Table V as they are, the increased money, 
value reeeived from spraying two-fifths acre was barely enough 
to cover the cost of spraying the same. It should be remembered 
that the yields for 1899, previous to spraying, showed that the 
yielding capacity of this field as a whole was very small. The
