a number of the injured carnation plants. The information given 

 me was to the effect that the plants had been growing in a green- 

 house, that upon one day they were alive and well, and that four 

 days later nearly every plant was killed, including between two 

 and three hundred carnations. 



My examination of the soil showed the presence of notable quantities 

 of both lead and arsenic, and, on further testing the damaged carnation 

 plants, I obtained distinct indications of arsenic in them. I have 

 little doubt, therefore, that the injury to the plants was due to some 

 poisonous application. 



Though I endeavoured to follow up the inquiry, I could only 

 gather further that suspicion attached to a gardener on the establish- 

 ment.
