working on the subject with the Author's assistance, have succeeded 

 in preparing a paste which, when diluted with water, reproduces 

 a mixture which is practically identical both chemically and phy- 

 sically with the freshly-made Woburn Bordeaux except that it 

 contains no excess of lime. " The paste itself is not likely to be 

 made by growers, and it would not be fair on Messrs. Voss who 

 have devoted much labour to the perfection of it, that we should 

 give details as to how the many difficulties met with in preparing 

 it satisfactorily have been overcome." (Of this important public- 

 ation an Abstract is given in Nature, Vol. 83, March 3 1910, p. 13). 



Effect of carbon bisulphide on Wireworms. (Journal of South-

The usual practice in hop gardens, where wireworms are trouble- 

 some, is to trap them with pieces of mangold placed at the side 

 of each hill. This is a somewhat expensive operation and may 

 cost about five shillings per acre annually, so it was determined to 

 try an injection of carbon bisulphide. 



Two rows in the College garden were selected (S. E. College 

 of Agriculture at Wye), and the hills in one row were treated by 

 injecting two ounces of carbon bisulphide into each, at four points 

 about two feet away from each hill. The hills in the other row 

 were left untreated. 



The hills in each row were trapped with mangold in the usual 

 way, and after about three weeks the traps were pulled out and 

 the wireworms carefully counted. 



In eighty hills in the row treated with bisulphide there were 

 336 wireworms, whilst in eighty hills in the untreated row there 

 were 362 wireworms. This result shows that the injection of carbon 

 bisulphide is of very little use for wireworm in hops.
