REPORT ON MANURES, APPLIANCES, &c., 1908, 553 



in the evening. The appearance of the sky and the readings of the 

 instrument both indicated frost extremely unlikely. The temperature 

 steadily rose till midnight, when 44° was registered in the screen, and 

 as steadily declined to 43'5° at 2 a.m. ; but the sky then clearing, a 

 steady and rapid fall took place till the minimum was reached between 

 6 and 7 a.m., when 34° was registered in the screen and 28*4° on the 

 grass. 



22. Four Oaks Undent-able Syringes (Four Oaks Company). — These 

 are made in various sizes, suitable for coarse or fine spraying, and are 

 excellent in all respects. We do not know of any syringes that will stand 

 rough usage so well as these. 



23. Four Oaks Knapsack Sprayer (Four Oaks Company). — Consists 

 of a copper container of the usual form and size, but has all the working 

 parts outside, so that they are easily reached in case attention is needed. 

 The working parts are very strong, and a considerable pressure may be 

 maintained with a minimum of labour. The nozzle and brass tube 

 carrying it are connected with the pump either by a rubber tube or by 

 flexible metallic tubing. The nozzle gives a very fine spray. Two- and 

 three-way nozzles are also provided, but the single seems to give the best 

 results. 



24. Four Oaks Spraying Machine (Four Oaks Company).— This, like 

 the preceding, is a strong and serviceable machine. It consists of a 

 stout wooden container, mounted on a carriage with broad wheels, and 

 fitted with a powerful pump, which is capable of supplying two spraying 

 tubes. The pump drives out the liquid with great force. An efficient 

 agitator is fitted, the pump handle actuating the agitator as well. The 

 working parts are of brass, simple and strong and easy of access. The 

 nozzles are interchangeable with those of the knapsack sprayer, and may 

 be placed at the end of a long, light, hollow bamboo tube, by means of 

 which the highest orchard trees may be reached, or on the shorter tubes 

 which are provided.
