Ammoniaeal Copper Carbonate. 



Copper Carbonate 5 oz. 



Ammonia. 2 qta. 



Water 50 gals. 



This is prepared bj- dissolving the copper carbonate in the ammonia and diluting with 

 water to 50 gallons. The concentrated solution should be poured into the water. Care 

 should be taken to keep the ammonia in glass or stone jars tightly corked. 



This mixture is more expensive than the former, but is more easily applied and may 

 be used as a substitute, especially in the case of grapes where late spraying is necessary, 

 and when Bordeaux mixture might, by adhering to the fruit, injure its sale. 



Copper Sulphate. 



Copper sulphate, 1 lb. to '2o gallons of water, is used for the first application only. 

 It should never be applied after the buds burst, as it will injure the foliage. 



As a guide to readers in their operations, we give, on the next page. Prof. 

 Craig's Spraying Calendar^ which will be of intense interest to our readers, many 

 of whom will, we believe, follow it out in full. We shall be very glad to receive 

 reports for publication, showing the results of faithful work done in all parts of 

 Ontario. The trouble so far has been the careless half-hearted method of doing 

 the work, and, in consequence, no wonder at the failure of good results. 



The PePambulating Sprayer. — A scheme for demonstrating the impor- 

 tance of spraying for apple scab, codling moth, and plum and cherry rot, has 

 been devised by the Board of Control of the Fruit Experiment Stations of 

 Ontario, and approved by the Minister of Agriculture. Three sets of sprayers 

 are to be started, each under a competent man ; one set will travel through 'the 

 counties along the north shore of Lake Erie, from Windsor to the Niagara River; 

 another along the north shore of Lake Ontario, from Toronto to the St. 

 Lawrence ; and another along the east shore of Lake Huron. Mr. A. H. 

 Pettit, who formulated the scheme, is to be made the responsible director of 

 the whole work. 



Law for Fruit Packers — So much fraud has been perpetrated upon 



the public by dishonest fruit packing that legislation to prevent it is in demand. 



The growers of the Niagara district have met and discussed the matter, and all 



agree that some measures are needed to protect the honest grower from having 



his reputation soiled by dishonest men. How best to do it is the question. It 



s proposed, 



(1) To have apples and pears gratled No. 1 and No. 2 ; (2) to have all graded fruit 

 branded with the name and address of the packer ; (.3) in cas^ of ungraded fruit, that the 

 top layer shall be a fair representation of the whole contents of the package ; (4) to regulate 

 the sizes of fruit packages.
