which can be grown in the orchards of 

 Southern Ontario. The quantity to be sown 

 per acre depends somewhat upon the re- 

 quirements of the crop. A light cover crop 

 can be obtained from sowing one-half bushel 

 of seed per acre. A much better and thicker 

 matting can be formed by- sowing one bushel 

 per acre. For the production of fodder it 

 is customary to sow one and one-half bush- 

 els per acre, which amount usually produces 

 a large amount of fodder of excellent 

 quality. It will ripen its seed in Ontario, 

 but does not produce very large yields. The 

 highest yield which we have obtained has 

 been seven bushels of seed per acre. 



TREE PROTECTORS. 



Sir, — I want a little information through the 

 columns of the Horticulturist. I notice two different 

 advertisements for the tree protector advertised in 

 the Canadian Horticulturist. One is the Expansive 

 Tree Protector Co. of Ontario and the other is the 

 Tree Preservation Co. Will you please tell me which 

 is the best, or is any of them any good, or has any 

 leading fruit grower given them a thorough test, and 

 would I need to spray my fruit trees as well ; will- the 

 Aphis or any other insect get above the pi'otector ? I 

 would like to get particulars from some experienced

In replying to Mr. Bruce's inquiry regard- 

 ing the merits of the two tree protectors 

 which are advertised in the Canadian Horti- 

 culturist, I shall deal with the questions in 

 order. First, I cannot state which is the 

 better protector of the two, for I have not 

 had sufficient experience with them. Sec- 

 ond, that neither of them are useless, and 

 both possess some good features. Third, 

 many fruit growers have given them a thor- 

 ough test, and some of them recommend 

 them, but many others prefer the burlap. 

 Fourth, these tree protectors will not take 

 the place of spraying. Fruit trees must be 

 sprayed at certain intervals for the preven- 

 tion of fungus diseases and insects of many 



kinds, only some of which can be entrapped 

 by the tree protectors. The protectors will 

 not keep away fungi, and applications of 

 Bordeaux are necessary fcH* their control. 

 With regard to the Expansive Tree Protec- 

 tors, I may quote from an article which I 

 prepared for the annual report of the Ento- 

 mological Society for 1902. " Recently an- 

 other device for entrapping codling worms 

 has been put on the market. It is known 

 as the Expansive Tree Protector. It con- 

 sists essentially of an expansive metallic col- 

 lar, coated on its underside with a sticky 

 substance, and a cloth band saturated with a 

 poisonous liquid placed between the collar 

 and the trunk of the tree. Although not in 

 a position personally to test the device this 

 year, I had an opportunity of inspecting 

 many of them in different orchards. In 

 nearly every case they failed to give satis- 

 faction, and in some instances were positive- 

 ly harmful. In the first place they are diffi- 

 cult to fit to the trunk of the tree ; secondly, 

 the sticky substance did not hold the cater- 

 pillars, and other forms of insect life, or pre- 

 vent them from crawling over it; thirdly, 

 the poisonous band did not kill the insects 

 which crawled beneath the collar ; and 

 fourthly, the bark of the tree immediately 

 beneath the band was frequently seriously 

 injured. In my humble opinion, decided 

 improvements in the construction of this de- 

 vice must be made before it becomes effec- 

 tive." 



VEGETABLE GARDEN. 



Sir, — I have been reading your journal (the 

 Canadian Horticulturist) for two or three years and 

 always enjoy it very much. I have noticed the 

 " Question Drawer" and desire to ask a question or 

 two. My father has given me a large plot of ground 

 and I thought if I could make a vegetable garden 1 

 might make some pocket money. What vegetabL 

 would be the most remunerative ; also, is there any 

 market where I could sell sweet peas and field daisies '.' 

 I hope j'ou will be able to find time to reply soon and 

 that this isn't too much of an imposition on j'oiu 

 valuable time.
