AND HORTICULTURE. 43 
As the rule is certain that the better the vegetation the 
higher the increase per cent.,a good result was not to be 
expected, in consequence of diminished vegetation generally. 
But from another cause—viz., that the machine has none 
or little effect shortly before, during, and shortly after rain, 
a lowered result must be the consequence. From the 
majority of plants no harvest could be obtained, because they 
had not sufficient time to ripen ; others were destroyed by 
insects, and so on. It is therefore to be regarded as 
somewhat astonishing that the results have been as good 
as the following table shows :—

A chemical analysis of the sugar-beets made by Mr. 
S. H. Collins at Durham College of Science gave the 
following results :—

Or an increase of 2:21 per cent.—or 18:05 per cent. of . 
that of the control field—of cane sugar on the experimental 
field. This analysis agrees fully with an analysis executed 
in Burgundy in 1888. . 
One kind of plant, the rye-grass, gave a negative result; 
but as all the experimental fields were situated lower than 
the control fields, the former received the water flowing 
from the latter, and, during such a summer as that of 1902, 
the effect of this was considerable. The control fields had 
also the advantage of having been more recently manured,
