Compensation for Unexhausted Manurial Values. 109 
To make this clear, we have substituted for “First year,” 
“ Second year,” &c., in our Tables the terms “ Before one crop 
has been grown,” “After one crop has been grown.” As a rule 
the manure will have been made during the winter and be 
applied to the following spring or root crop. D (1) will 
accordingly, as a rule, mark the value of the manure as it is in 
the yards, D (2) after the root crop has been grown. 
In a case where the manure has been used for the root 
crop, and where this crop, though still on the land at the time of 
the giving up of the tenancy, has to be paid for by the in-coming 
tenant, the value is indicated by column D (2), for the manure 
has been used for the crop, and is clearly not of the same 
value as when lying in the yards, but is only the residue left 
after the taking out by the root crop of what the latter will 
utilise. 
Storing of Manure. 
Another point upon which there has been misunderstanding 
is in regard to the conditions under which we presume the 
manure to have been made at the time it is valued, and the 
precautions against loss that should have been observed in 
the making and storing of it. We would state clearly that 
our Tables, as set out, presume the manure to have been made 
in boxes or yards where there is no avoidable loss by drainage, 
and where the manure is not washed by rain ; further, that 
the manure has been made w T ith all reasonable care, and that it 
has been stored, protected from the rain, and not unduly 
exposed or otherwise subjected to loss. 
We have shown in our original Tables that even under ideal 
conditions, such as those which existed at Woburn (where the 
manure was made in pits with cemented bottom and sides, and 
was, after removal, covered with earth) there was an unavoid- 
able loss of from 30 to 35 per cent, of the original manure 
value as calculated from the composition of the materials used. 
Reckoning that these conditions would not be obtained in 
ordinary practice, we followed Lawes and Gilbert in their 
estimate that the loss would be about 50 per cent, under 
ordinary good farming conditions, and our Tables are based on 
this assumption. When these conditions have not been com- 
plied with, and the manure has been made in open yards and 
has been exposed to rain, so that the liquid portions may to a 
great extent have drained away, or where the manure has been 
left exposed in uncovered heaps in a field and the washings 
have sunk into the earth around, it is clear that the losses may 
be still more. 
It is impossible to frame separate scales for all such sets of 
conditions, and this is a matter on which the valuer must exercise
