THE MARKET VALUE OF THE DIFFERENT 
SAMPLES OF WHEAT AND BARLEY GROWN 
IN 1889 ON THE EXPERIMENTAL PLOTS AT 
ROTHAMSTED. 
{Communicated by the Lawes Agricultural Trust Committee.) 
The experiments on the continuous growth of wheat and barley at 
Rothamsted were designed and have been carried out for the deter- 
mination of scientific problems. It was no part of the plan to 
discover how to produce the largest and best crops, or to determine 
the most profitable manuring for different crops. Yet the investi- 
gations have supplied in their course many results which have been 
of practical value to the farmer. The annual estimates of the 
average wheat crop of the United Kingdom, published by Sir J. 
Bennet Lawes, have been based on the produce of the experimental 
crops in Broadbalk field. 
The Lawes Agricultural Trust Committee wished to ascertain 
the commercial value of the wheat and barley from the plots 
harvested in 1889. With this view they obtained the assistance 
of a skilled valuer who examined all the samples and reported to 
the Committee, Dr. Gilbert supplying some observations on the 
valuer's report. The Committee resolved to oiler the report ami 
observations to the Royal Agricultural Society for publication in 
their Journal, and placed the documents in the hands of a sub- 
committee (consisting of Sir J. H. Thorold, Mr. Whitehead, and Mr. 
Carruthers) to prepare a statement of the results suitable for pub- 
lication. 
The only matter that is new in this communication is the 
market value of the crops. Though it is impossible in perusing 
the data here given to avoid reading the lessons which they teach, 
it is most necessary to bear in mind that the data refer only to 
one year, and that the observations of future years may greatly 
modify the conclusions legitimately proceeding from those of 1889.
