48 First Report on Economic Zoology. 
Treatment. 
The bushes should be sprayed with cupram and Bordeaux mixture 
some time before and after harvesting ; the first application should be 
about two weeks before the rust spots usually appear. 
Bordeaux mixture may stain the fruit, so that for an early washing 
before the fruit is picked cupram had best be used, and Bordeaux 
mixture after harvesting. 
Neither should be used for three weeks before the fruit is gathered 
as they are to a certain extent poisonous. 
Preparation of Cupram. 
Measure out J pint of strong ammonia (avoid the fumes), and 
add it to 2 quarts of water. Weigh out 1 oz. of carbonate of copper, 
wrap it up in a piece of copper gauze and suspend it by a copper wire 
in the ammonia liquor. Let it remain all night. When required for 
use dilute the blue fluid with 12 gallons of water. This is the best 
fungicide for all ripening fruit. 
Bordeaux Mixture.

10 gallons. 
Dissolve the copper in 10 gallons of water, boil the lime and 
treacle with a quart of water for half an hour. When dissolved, mix 
them together and stir them up well. The mixture is then ready 
for use. 
Gooseberry Fungus. 
(. Puccinia pringsheimiana, Kleb.) 
The gooseberries and leaves sent are attacked by a fungus. This 
fungus is the secidium stage of Puccinia pringsheimiana of Klebahn. 
The cluster cups or aecidia occur on the gooseberry, both on the 
leaf and fruit ; the other stages affect certain species of Carex (sedges). 
It is generally seen in damp places, but is rarely in sufficient 
abundance to do any practical harm. As in the present case it is doing 
considerable damage, any further notes will be gladly received.
