APPLIANCES &c. TESTED AT WISLEY, 1905. 



Automatic Ventilator (Gardiner). This ventilator acts on the hydraulic 

 principle, the pressure being obtained from a sensitive fluid, hermetically 

 sealed in three tubes. When the temperature rises above any figure at 

 which the apparatus may be set, the fluid expands, bringing pressure to 

 bear on the sliding tube fitted to the lever opening the ventilator, opening 

 the same ; as the temperature falls, the contraction of the fluid causes 

 the ventilator to close. Since the apparatus was fixed in November, it has 

 worked fairly well, but the real test of its value or otherwise cannot be 

 determined until warmer weather sets in. 



Anti-Blight (Anti-Blight Co.). A very useful and effectual wash for 

 aphis, thrip, or American blight (woolly aphis). 



La Foudre (Cadic). A chemical manure applied at the rate of 1\ oz. 

 per square yard superficial. This was applied to broccoli plants, without 

 any apparent results. This may arise from the dry season of 1905. 



Lamp and Eurekatine (Tomlinson & Hay ward). A liquid that is 

 placed in a small dish over a lamp, filling the house with a vapour deadly 

 to insect life, but perfectly harmless to tender foliage or flowers, provided 

 the instructions sent with each bottle are carried out properly. 



Eurekatine (Tomlinson & Hayward). An excellent insecticide for 

 syringing or dipping plants infested with aphis. 



Patent Incisor (Luzy Freres). A small instrument for " ranging " 

 shoots or branches bearing fruit. It is claimed that by this process 

 ripening of the fruit is hastened, the fruit is increased in size, and the 

 quality is improved. As the fruit crop was a failure in 1905 at Wisley, 

 this could not be tested. 



Patent Infuser (Levi). A vessel with perforated sides in which manure 

 is placed, and plunged in a tub or tank of water, to make liquid manure. 

 It answers this purpose very well, but is not superior to the old-fashioned 

 method of filling a sack with manure in a tank. 



Baffiatape (West). A strong, durable, and excellent tying material on 

 reels ; the colour is a grass-green, and is scarcely noticeable, being about 

 the same colour as the foliage. 



Kusticide (Dicker). This is not only first-rate for destroying "rust" 

 on plants, but is a very good insecticide for killing aphis. 



Syringe, Sale's Patent Grit-proof (Sale). For use in the ordinary way. 

 This syringe is rather too light to work comfortably, but where fine spray- 

 ing is wanted it does its work admirably. 



Sprayer and Insecticide (Holland). An unnamed liquid insecticide. 

 Applied in the form of spray, it has proved deadly to red spider, aphis, 

 and thrip, without the slightest injury to foliage. 



Slugdeath (Stanley). This is the finest destroyer of slugs we have 

 tried, either in a liquid or powder form. Put on according to the instruc- 

 tions supplied, it kills all the slugs, with no injury to the plants.
