Home-Made Soluble Oils 



"Home-made Soluble Oils for Use against 

 the San Jose Scale," is the title of Bulletin 

 179, issued by the Virginia Agricultural Ex- 

 periment Station. From tests made at this 

 station, the following conclusions are 

 drawn: 



Home-made soluble oils are recommend- 



ed for trial in place of the lime-sulphur 

 wash, under certain conditions. Further 

 tests must be made before we can recom- 

 mend them unreservedly. For general or- 

 chard spraying the lime-sulphur is probably 

 more satisfactory. 



The various prepared or patented brands 

 of soluble oils cost about three times as 



Soutrette 



Was it the Song or the 

 Singer that you liked? 



Often the singer's personality is charming, but it is 

 the song you want. 



You get every inflection of the voice, every vocal 

 expression in the Edison Phonograph. Wonderful 

 progress has been made in the perfection of the Edi- 

 son Phonograph, until it is today the most perfect 

 sound-reproducing instrument. The latest invention is 



AMBEROL RECORDS^/- 



^^ EDISON 

 PHONCXiMPH 



— the Records which play four minutes instead of two. They 

 are no larger than the regular Edison Records, and can be 

 played on any Edison Phonograph (except the Gem) now in 

 use by means of an attachment which, however, will not 

 interfere with pla5dng the Records you now _ - 



have. If you buy a new Phonograph, it has 

 the attachments to play both Records. Hear 

 the Edison at a dealer's today. 



P^EE. Ask your dealer or write to us for illustrated catalogue of 



t-dison Phonographs, also catalogue containing complete lists of 



tdison Records, old and new.

much as the home-made product containing 

 the same per cent, of oil. Our tests indicate 

 that the home-made oil is as effective as the 

 prepared oil. The cost of the home-made 

 oil is about the same as the cost of lime- 

 sulphur. 



The home-made soluble oil is more prac- 

 ticable for the practical orchardist than 

 for the man who has only a few trees, unless 

 one person will make the material for a 

 neiehborhood. 



It is not quite as troublesome and dis- 

 agreeable to make soluble oil at home as it 

 is to make lime-sulphur. 



Apply the soluble oil spray only in the 

 dormant season. The trees should not be 

 pruned before they are sprayed, as the oil 

 may injure the cut surfaces, unless they 

 are painted. 



The home-made soluble oil sprav is re- 

 commended for trial apainst the San Jose 

 scale, and the maple scale. It is not recom- 

 mended for use against the scurfy scale. 



Short Course at Guclph 



A. J. Logsdail, Ontario Agricoltoral College 



The short course in fruit growing that 

 was held at the Ontario Agricultural Col- 

 lege early in February wiis a great success. 

 In addition to the discussions referred to in 

 the March issue of The Canadian Horti- 

 culturist, the following addresses and con- 

 ferences were of great value and interest: 



Mr. T. D. Jarvis gave a short illustrated 

 lecture showing the difference be- 

 tween the two great classes of insects, 

 namely those that feed by chewing or biting 

 their food, and those that feed by sticking 

 the juices of plants or trees. Mr. L. Ca<^sar 

 also of the entomoloeicnl denartment then 

 briefly discussed the best m'-thods of deali'ig 

 with many of the most injurious insects 

 to fruit. 



SPRAYING 



There was a general conference on the 

 preparation and application of spraying 

 materials. Bordeaux mixture was made \x\. 

 in barrel lots and its physical properties 

 determined. Lime-sulphur was next madt 

 up in the following ways: 15 lbs. of sul- 

 phur, 20 lbs. of lime and 15 gallons of 

 water was steam boiled for one hour then 

 made up to 40 gallons; 15 lbs. of sulphur, 

 l,") lbs. of lime and 15 gallons ot water wa? 

 boiled for one hour and made up to 40 gal- 

 lons; and lastly 15 lbs. of sulphur was made 

 into a paste and then mixed with 20 lbs. of 

 unslacked lime over which two gallons of 

 hot water was poured, this was then allowed 

 to self boil for 40 minutes. A chemical 

 analysis was made of these three combina- 

 tions and it was found that the 15-20 formu- 

 la contained about 13 per cent, of calcium 

 sulphide, the 15-15 formula contained about 

 12 per cent, and the self boiled under 2 pei 

 cent. From these figures it will be seen 

 that the two steamed boiled sprays were 

 considerably stronger than the self-boiled, 

 but the self-boiled it has been shown is 

 much less liable to injure foliage and servos 

 splendidly as a summer spray. 



Profes.sor John Craig, ot Cornell Univer- 

 sity. N. Y.. gave a most interesting lecture 

 on the methods of apple-growing in British 

 Columbia, and the states of Washington 

 and Oregon. 



THE BEST VARIETIES 



That best varieties for one section would 

 not necessarily be the best for other dis- 

 tricts, was pointed out in a discussion on 

 this subject. Mr. J. E. Johnson, of Simcoe, 

 named the following as his choice for Nor- 

 folk county: Baldwin, Spy, King, Snow, 

 Greening and Mcintosh. He deplored the 

 old method of planting numerous varieties, 

 a mi.xed lot of fruit being much harder to 

 dispose of profitably than a few first class
