 years at various subjects of research, especially the cross-breeding

 result he was elected a Fellow of his College, and returned to

 book ' Variation, Hereditv, and Evolution,' published by Murray

 created for him. He held the office till 1912, having come home 

 on leave in 1910 to be married, and took the degree of Sc.D.

 breeding, and as one result, ]n'oduced a new strain of rice, now 

 known as Lock's Padd}^ which is displacing other varieties in the 

 island. 



Meanwhile changes took place in the administrative circles ; 

 the government had decided to create a Department of Agricul- 

 ture and put the Director of the Peradeniya Gardens under the 

 Director of Agriculture, and the Garden post was offered to 

 Dr. Lock. He found himself unable to accept it, and returned 

 to Cambridge, wrote a small book on rubber for the University 

 Press, and then became an Inspector under the Board of Agri- 

 culture and Fisheries, in charge of the district round Birmingham, 

 including the fruil and hop-growing districts in Worcestershire 

 and Herefordshire.
