The use of arsenical sprays may prove a danger to health. Fruit 

 trees were sprayed with Bordeaux mixture and with a solution con- 

 taining Paris green. An examination made 40 to 50 days after a single 

 application of Bordeaux mixture, showed an appreciable amount of 

 arsenic on currants and gooseberries. This was also the case with 

 apples and pears examined 87 days after two applications had been 

 made. The leaf -tissues behave in the same way as regards the absorp- 

 tion of arsenic, while leaves and fruit examined in order to ascertain 

 their lead content, also gave similar results. Paris green solutions 

 behaved in practically the same manner.

According to Dr. R. Meissner, of the Weinsberg Agricultural Experi- 

 ment Station, in Wurtemberg, the best results against vine-moth 

 [Clysia ambiguella and Polychrosis botrana] are given by a 1^ per cent, 

 solution of nicotine. This did not cause any scorching in 1914, in 

 which year the tests were made.

The control of Eulecanium {Lecaniunt) corni {vini) on currant and 

 gooseberry bushes may be easily and cheaply effected by spraying 

 towards the end of March or at the beginning of April with a 3 per cent, 

 solution of soft soap. Complete destruction of the scale necessitates 

 several apphcations during the spring.
