THE CANADIAN HORTICULTURIST. 



used, giving a steady pressure of about lOO 

 pounds, with a 200-gallon tanJ< and two 

 Tines of hose, carrying six nozzles each. 

 Qu'arter-inch hose was uSed for the sake of 

 Hghtness and was found very satisfactory. 

 The Bordeaux mixture (with paris green 

 added) was the only one applied, except in 

 one or two cases towards the end of the 

 season. 



WORK WILL BE TRIED IN NOVA SCOTIA. 



Arrangements are being made for carry- 

 ing on a similar demonstration this season 

 in the Annapolis Valley, N.S., where Inspec- 

 tor Vroom has charge of the preliminary ar- 

 rangements ; and near Ingersoll, Ont., under 

 the direction of Mr. J. C. Harris. It need 

 hardly be said that the fruit division 'will not 

 make a permanent business of spraying or- 

 chards for owners. The object of the 

 demonstrations is to induce growers to unite 

 in groups, wherever 3,000 or 4,000 trees can 

 be had within a distance of about five miles 

 from end to end. Such a combination of 

 growers could afford to purchase an outfit 

 among them at a cost of something like $350, 

 or to hire the use of such an outfit from its 

 owner, who might undertake to do the work 

 thoroughly, at so much per tree. 



Power spraying, it is hoped, will be taken 

 up either on the co-operative basis or by 

 men such as the threshermen, who could 

 give their whole time during two or three 

 months to this work, at a profit both to them- 

 selves and to the growers. One efficient 

 man, who understands the preparation of 

 spraying mixtures, who can learn how to 

 manage a gasoline engine, and who can be 

 depended on to do the work thoroughly at ' 

 all times, will be sufficient for each group of 

 orchards. He may require two or three 

 assistants to drive and hold the lines of hose, 

 but they need not be skilled, as he will direct 

 the entire work. 



THE ONLY LIKELY WAY. 



It does not seem likely that in any other 



way spraying will become general through- 

 out the country, and it is hoped that this 

 method, overcoming as it does most of the 

 objections to spraying either by power or 

 hand, will eventually, lead to a great im- 

 provement in the average quality of the 

 apple crop of Canada. 



Already as a result of the successful 

 operation of the Woodstock outfit at least 

 one fruitgrowers' association has ordered a 

 power spraying outfit, and other groups of 

 orchardists, as well as some large owners, 

 are contemplating such a purchase. Grow- 

 ers appear only too eager to have the work 

 done for them even if it costs them more 

 than they have formerly been able to do it 

 for. Mr. Harris, of Ingersoll, states that 

 he could easily have taken orders sufficient 

 to keep two outfits busy in his immediate 

 neighborhood, though growers are asked to 

 pay the actual cost, about the five cents per 

 " tree-spraying." A group of King's 

 county growers in Nova Scotia have made 

 similar agreements for four sprayings dur- 

 ing the present season, and there would 

 have been no difficulty in securing a great 

 many more orchards. It would appear, 

 tiierefore, that new as the method is, it has 

 appealed to the common sense of the grow- 

 ers, and there can be no doubt that they will 

 very soon adopt it on their own account. 



Examine the Apparatus. — Our spray- 

 ing apparatus is overhauled a few days be- 

 fore we intend spraying. The hose and noz- 

 zles are examined carefully, for it does not 

 pay to have " breakdowns " in the spraying 

 season. The Bordeaux and ' paris green 

 mixture is made very carefully, and the 

 ferrocyanide test is always made to deter- 

 mine whether sufficient lime has been used. 

 The agitator of the spray pump must be 

 carefully looked after to see that it really 

 agitates the liquid and keeps the paris green 

 in suspension in the Bordeaux mixture. —
