Utilisation of Toton Sewage. 
the experiments (1861), bj the previous tenant ; it had been fed 
down very close hy sheep and other stock, up to nearly the end 
of March ; and the application of sewage, under the direction of 
the Commission, did not commence until April 1. Unfor- 
tunately the amount of sewage available in this field was very 
much less than was desired, so much so that the plots on the 
portion allotted to be cut green for milking cows did not receive 
the quantities intended, even though, after a few weeks, the 
application on the portion devoted to hay was entirely aban- 
doned, in the hope of securing enough for the other. 
" In both fields, owing to derangement and repair of the 
works, the supply of sewage was very inadequate during portions 
of the growing months of May and June. 
*' The upper portion of the Table (II.) shows the distribution 
of the produce of the respective plots throughout the season, 
according to the amounts of sewage applied ; and the lower part 
shows the amounts of produce yielded in each successive crop 
under the same variation of circumstances. The results, as 
given in the upper portion, show not only how very much more 
total produce was obtained by the application of sewage, but 
also over what a much more extended period of the season an 
abundance of green food was obtainable when large quantities of 
sewage were applied ; and it should be observed that, in both 
fields, plots 3 and 4, to which the largest amounts of sewage 
were applied, might with advantage have been cut earlier, and 
they would then have yielded much larger crops during May 
than are recorded for that month. On the other hand, in some 
cases not inconsiderable amounts of produce were obtained even 
as late as November. It is, however, probable that, in practice, 
it will not be advantageous to cut later than October ; and it was 
only done in this case as a means of better estimating the quan- 
tity of the produce yielded. The lower portion of the Table 
shows that there is, in almost every case, an increase of produce 
at each successive cutting with each increase of sewage applied. 
It will be seen further on that the produce of the earlier cuttings 
contained a larger proportion of dry substance than that of the 
later ones ; arid also that the sewaged grass differed considerably 
both in the proportion and composition of its dry substance 
according to the (juantities of sewage applied, and still more 
from the unsewaged grass. 
" The proportion of produce obtained to sewage applied is 
better seen in Table III., where the amounts of sewage intended,- 
and actually applied up to the end of October, the amounts of 
total produce, and the amounts of increase of produce for each 
1000 tons of sewage applied, are given side by side.
