It saves a great deal of trouble in mixing, and also risk of careless 

 workers breathing in the powder, to use it in the damped form, which 

 can be procured as well as the dry powder from Messrs. Blundell, 

 Spence & Co., of Hull, and 9, Upper Thames Street, London. 



The Paris-green spraying should of course never be used on plants 

 when in flower, or it would injure the blossom; but with regard to 

 any probable injury to animals, though we certainly always most 

 scrupulously advise none should have access where there is a chance 

 of Paris-green havmg fallen, still it is to be observed that where 

 this has occurred, we cannot find that, in the small quantity in 

 which only it can be serviceably used to the plants, any evil 

 consequences at all happen to animals pasturing, or feeding where 

 drip might fall. 



One observer fed his mares and foals beneath the Paris -greened 

 trees with no ill effects ; another allowed his fowls free run under trees 

 repeatedly sprayed ; and in a very specially watched experiment, 

 reported to our Evesham Fruit Growers Committee (during our first 

 trials of effects of Paris-green), regarding the condition of a rabbit kept 

 so as to have full injury (if any was caused) by " green" falling from 

 the sprayed trees, it appeared on enquiry that the animal continued in 

 excellent health, and, as it was further remarked, brought up a large 

 family with great success ! 



The circumstance of Paris-green having now been regularly used 

 over an enormous area of country in North America, as the effectual 

 means of keeping down the Potato scourge, commonly known as the 

 Colorado Beetle, is a strong reason for hoping that we might find it 

 very serviceable for use against Mustard Beetle. The two kinds are 

 very nearly allied, and both feed on the plants in grub as well as 

 beetle state, and are consequently both open to similar remedial 

 measures. 



labelled Poison and kept locked up, and especially kept safely out of the way of 

 children, who might be attracted by the beautiful green colour of the powder. 



Workers with the powder should not allow it to settle in any sore or crack in the 

 skin of the hands, nor stir it about unnecessarily with the hands ; and they should 

 be very careful not to breathe in the x>owder through mouth or nose whilst measuring 

 or mixing it. 



For this reason it is most desirable that purchasers of Paris-green should have 

 it sent not in bulk, to be divided for use on receipt, but wrapped in single pound (or 

 small) packages by the senders, or, what is better still, have it in form mentioned 

 above as "Paris-green paste," that is, the powder just damped so that it cannot 

 liy about. If swallowed in any quantity by being drawn in with the breath it would 

 certainly be harmful. An instance is on record in which a man employed to weigh 

 out and wrap 5 cwt. in 1 lb. papers lost his life therefrom. But with the most 

 ordinary care the application may be mixed and used, as well as hellebore and other 

 poisons often applied in orchard and other farming work, with perfect safety.
