THE CANADIAN HORTICULTURIS2 



However, when, by reason of numbers, 

 this operation becomes impracticable, resort 

 must be had to spraying solutions. Kero- 

 sene emulsion and whale oil soap solutions 

 are perhaps the most effective. The stand- 

 ard kerosene emulsion should be diluted 

 with ten parts of water if used alone. Some 

 authorities recommend the use of the mix- 

 ture — the standard emulsion is diluted with 

 one pound of fish oil dissolved in ten gallons 

 of water. 



The best time to apply the mixture is 

 about the first or second week in July, when 

 the young lice emerge from the eggs. They 

 are then easily killed. Winter or fall treat- 

 ment is also valuable. The same substance 

 may be used, but the solutions should be 

 stronger than, those used in summer. 



In some cities where the cottony scale 

 made its appearance good results were se- 



cured by applying a strong stream of water 

 against the cottony sacs when they con- 

 tained the eggs, and before these hatched. 



By reason of the abundance of parasites 

 this pest is seldom troublesome more than 

 two seasons. 



PROPAGATING CLEMATIS. 



Sir, — I have a thrifty Clem- tis Jackmanii. Can 

 I propagate it by labeling, and wi en would be the 

 best time? G. S. W. 



Hawkesbur)-, Ont. " 



Answered by Prof. H. L. Hutt, O. A. C, 

 Guelph. 



The Clematis can be readily propagated 

 by layering the young shoots any time now 

 after the wood has become somewhat ma- 

 ture. The new vines should be covered 

 with a couple of inches of rich earth and 

 should be kept moist until the roots have 

 formed.

Proceedings of the New Jersey Horticul- 

 tural Society for 1903. — A verbatim report of 

 265 pages of the 28th annual session of that society 

 held in January of this year. This report contains 

 much valuable information, given in the 

 form of questions and answers, and the prompt- 

 ness with which it is published makes it of 

 additional value to those interested. 



The 28th Annual Report of the Ontario 

 Agricultural College and Experimental Farm 

 for 1902. — This report is made up of seventeen 

 parts, written by the heads of the various depart- 

 ments, and contains valuable information on a 

 wide range of subjects. Probably that of most 

 interest to our reader? will be found in the Report 

 of the Biologist and Horticulturist. A copy oE 

 this report can be obtained by applying to the 

 Department of Agriculture, Toronto. 



The Woodlot, a Handbook for the Owners 

 of Woodlands in Southern New England. (Bul- 

 letin No. 42, Bureau of Forestry, U. S. Depart- 

 ment of Agriculture.) This is another of those 

 valuable publications on forestry which the U. S. 

 Department of Agriculture sends free to those 

 interested in the care of private woodlands. The 

 purpose of the bulletin is to show how second 

 growth woods should be treated in order to yield 

 larger returns in the long run than is possible 

 under other methods. Thirty full page diagrams 



are given, showing examples of typical cuttings in 

 thinning timber. 



The Ninth Annual Report of the Fruit Ex- 

 periment Stations of Ontario. — To those inter- 

 ested in fruit growing in Ontario this is one of the 

 most valuable reports published. It contains 

 reports from fourteen fruit experiment stations, in 

 as many different parts of the province, on all 

 classes of fruits grown in the country. Careful 

 notes are given on varieties new and old, and 

 many of the newer ones are shown in beautiful 

 photographic illustrations. This report can be 

 obtained free upon application to the Department 

 of Agriculture, Toronto. 



Lectures on Forestry, by B. E. Fernow, LL.D. 

 — This is a little booklet of 86 large pages, con- 

 taining the ten lectures on forestry delivered by 

 Dr. Fernow at the Kingston School of Mining last 

 winter. The lectures are excellent, and cover in 

 a general way the whole subject of forestry. It is 

 also well illustrated and is well worth the price at 

 which it is offered, 25c. The writer of the intro- 

 duction, however, makes a mistake in trying to 

 give Queen s Univeisity the credit for thus being 

 the first to make a beginning in Forestry education 

 in Canada. He probably was not aware that 

 forestry has been regularly taught at the Ontario 

 Agricultural College for the past twenty 

 years.
