 might correctly call them who had spent their lives in the study 

 of the best means of improving the yield and quality of agricul- 

 tural crops Sir John Bennet Lawes and Mr. Joseph Henry Gilbert. 



We have already given, in a sketch of J. B. Lawes, in Volume 

 XXVIII of The Popular Science Monthly, a brief account of the 

 early history of the Rothamsted Agricultural Experiment Sta- 

 tion. 



It was established by Mr. Lawes on the estate which he en- 

 tered by inheritance in 1834. He had been engaged for several 

 years in chemical experiments, chiefly with reference to the prepa- 

 ration of drugs. As he wrote to a friend in 1888, he had not 

 thought of any connection between chemistry and agriculture till 

 his attention was attracted by the remark of a gentleman, who 

 farmed near him, that on one farm bones were invaluable for the 

 turnip crop, and on another farm they were useless. A quantity 

 of precipitated gypsum and spent animal charcoal was offered 

 him ; he was using much sulphuric acid in his drug experiments ; 

 and here he had materials for applying superphosphate and 

 enlarging and extending to the field experiments which he had 

 begun with plants in pots. In 1843 Mr. Joseph Henry Gilbert 

 became associated with Mr. Lawes, and the experiments have 

 been continued since then without interruption under the joint 

 direction of the two. The celebration we have mentioned was 

 held to commemorate the fiftieth anniversary of this connection 

 and of the beginning of the real work of the Rothamsted Station. 

 Both men were entitled to equal honor in remembrance, and both 

 received it in the tributes which were offered. 



Mr. GILBERT was born at Hull, August 1, 1817. His father was 

 the late Rev. Joseph Gilbert, and his mother was well known as 

 an author, under the name of Ann Taylor of Ongar. After
