for considering in what ways, if any, alterations in the plan of 
experiment might, with advantage, be made. I was accordingly 
requested by the Chemical and Woburn Committee to go into 
this matter and submit any proposals I had to make. This I 
did, and the suggestions meeting with the Committee’s 
approval, were carried into effect as from the crops of 1907. 
It will be within the recollection of many that the Woburn 
Field Experiments were originally designed (in 1876-77) to 
supplement the older Rothamsted Experiments of Lawes and

soil, the light sandy soil of Woburn was chosen for the new 
series, and to enable an answer to be given to the oft-asked 
(question whether the striking results brought out in the 
Rothamsted Experiments would be found to hold good on a 
soil of totally different character. It is now a matter of history 
that the results of the Rothamsted Experiments have found
