depth required, and, after planting, the turf is returned to its former 

 position, and the lawn left as before. 



The Holder Compressed Air Sprayer (Hartjen & Co.). 



A well-made copper knapsack compressed air sprayer with pump 

 and pressure gauge attached. It can be easily filled and manipulated 

 and gives a good mist-like spray, but the tube supporting the nozzle is 

 too short for safe use with caustic washes. 



Syringe (Boundary Chemical Co.). 



This is an excellent syringe fitted with a suction pipe of rubber 

 intended to dip into a pail standing on the greenhouse floor, so that 

 time may be saved in spraying or syringing. It would be useful in 

 a small greenhouse, but we think there are handier pieces of apparatus 

 for the purpose of spraying. The nozzle delivers a fine spray. 



Four Oaks Knapsack Sprayer (Four Oaks Company). 



We have already favourably reported upon this excellent machine 

 (vol. xxxiv. p. 553.) The form now reported upon includes several 

 small improvements upon the older one tending to greater efficiency in 

 working. The working parts are all easily reached and very simple. 

 The machine is so well made that it can scarcely get out of order, 

 and if it does it can be repaired with little loss of time. It is difficult 

 to see where improvements in this type of machine could be made, for 

 the principle of it, the materials, and the workmanship are of the 

 best. The nozzles, which are interchangeable with those of the 

 larger machines, are of various types for different grades of work, and 

 are very efficient. 



Four Oaks Spraying Machine (Four Oaks Company). 



Where a larger machine is required this oak tub mounted on a large- 

 wheeled, wide-tyred carriage, fitted with a strong and powerful pump, 

 and an ef&cient agitator is just tlie thing required. Its width enables 

 it to be used between rows of bush fruits, and its mechanism, together 

 with the excellent nozzles made by this firm, equalling, if not sur- 

 passing, the best our American cousins, who have studied the 

 question of spraying so largely, have produced, fit it for all sorts 

 of efficient fruit-tree spraying.
