REPORT OF THE EOR'ICUTURIST 43 



SESSIONAL PAPER No. 16 



1895, practical demonstrations in spraying were given in tlie province of Quebec, 

 and experiments against Apple Spot were conducted at two places in Ontario under 

 the direction of the Horticulturist. Experiments were conducted to determine the 

 effect of Lysol in preventing Peach Curl. 



1896, experiments with various combinations of leading fungicides and insecti- 

 cides with a view to preventing the cracking of pears, Apple Spot, and the late brood 

 of Codling Moth. 



1897, experiments with Lysol were continued. Use of arsenate of lead against 

 Codling Moth. Paris green with Bordeaux mixture found as effective as when used 

 alone. Experiments for the prevention of Peach Leaf Curl, Emit Kot, and Orange 

 Eust of quince. Various formulas tried to destroy aphis. 



1899 — An experiment was tried to prevent the swelling of the buds of apples, 

 plums, and cherries by spraying the trees with a lime-wash. The effect of this wash 

 on the oyster shell bark-louse was also noted. In this year the horticulturist assisted 

 the chemist in an experiment to destroy mustard by spraying with solutions of sulphate 

 of iron and sulphate of copper. 



1900 — Experiments with different formulas of lime-wash were made to test their 

 effect in eradicating Oyster-shell Bark-louse and San Jose Scale. 



1901 — Further experiments in the eradication of Oyster-shell Bark-louse with 

 lime-washes. Experiments with Bordeaux mixture for the prevention of potato blight. 



1902 — Experiments with potassium sulphide to check gooseberry mildew. Spray- 

 ing potatoes with Bug Death, wet and dry, and with Bordeaux mixture for the pre- 

 vention of blight. 



1903 — Test of dust sprayer. Experiments with different fungicides for potatoes 

 continued. 



1904 — Experiments with Bordeaux mixture, Bordeaux mixture and Bug Death 

 and Soda Bordeaux, to control potato blight. 



1905 — The same fungicides were used for potatoes as in 1904. An experiment 

 was made in conjunction with the Chemist in making kerosene emulsion with lime 

 and with flour instead of soap, and trying the effect of these emulsions on foliage 

 and on aphis. 



Spraying calendars prepared by the Horticultvirist and the Entomologist were pub- 

 lished in 1895, 1897, 1899, and 1904, in which directions are given for making the 

 different formulas recommended, and the time of spraying for each important disease 

 and insect pest. 



FORESTRY. 



The forest belts at the Central Experimental Farm, comprising about 21 acres, 

 are in the Horticultural Department. In these belts, which contain most of the best 

 native species used for timber, are growing about 23,000 trees. The trees are in blocks 

 of single species and in mixed plantations. The first planting was done in 1887. 

 Measurements are taken each year of the growth and height of certain average trees, 

 and tables showing these have been pviblished from time to time in the reports of the 

 horticulturist. 



Until the last few years the trees in the mixed plantations were making the most 

 satisfactory growth, and are still making better growth than some of the trees in 

 clumps of single species, but the rapid growing kinds are developing so fast in the 

 mixed belt that they are overshadowing some of the more valuable trees, and those 

 which cannot endure shade are being killed. To some extent this over shadowing is 

 prevented by clearing the side branches and letting in more light, and by heading back 

 some of the trees of less value. In nature the proper proportion of fast and slow 

 growing shade-enduring and light-needing trees is gradually adjusted as the trees 

 develop, but in artificial planting it is very difficult to arrange them in proper pro- 

 portion, especially where a large number of species are used. The fewer kinds that
