AGRICULTURE. 



Last year Mr. Falla, of Gateshead, Northumberland, trans- 

 planted from a seed-bed to a piece of land worked by the spade, 

 wheat which he ranged into rows six inches apart: this yielded 

 seventeen coomI)s per acre. Another piece of the land on which 

 the rows were planted twelve inches apart, yielded fifteen coombs. 

 Another piece sown in drill, and a fourth in broad-cast, yielded 

 nineteen coombs per acre. The produce of this land by plough- 

 ing is usually about six coombs. 



A field of seven acres, in the county of Surrey, was prepared 

 last year by the spade for barley. The labourers earned in the 

 winter at the rate of 15^. per week, two-pence per rod being 

 paid (or digging; and the proprietor believes it would have cost 

 him double the expense if he had ploughed it. 



IODINE IN SPONGE. 



M. Straub has ascertained to a certainty, that iodine exists 

 in sponge. Burnt sponge was washed with water, the solution was 

 decomposed by sulphuric acid, and enough of iodine v/as obtained 

 to confirm the idea tliat the medicinal properties ascribed to 

 the sponge, are owing to the presence of tliis substance. He 

 therefore recommended that preparations of iodine should be 

 tried in medicine, or an alcoholic extract from burnt sponge, in 

 preference to tiie burnt sponge itself. — He has also detected 

 iodine in turf, — Bib. Univ. xiv.
