night, and a further light watering followed the 

 application of the sulphate solution. " Three additional 

 treatments were given, four in all, at intervals of a 

 week, and only two puff-balls were gathered on the 

 whole green after the second dose, though before the 

 first it would have been no hard task to collect a 

 barrowful. Since the third treatment no puff-balls 

 have been seen on the green, and two whole seasons 

 have passed with no trace whatever of anything in the 

 shape of a fairy ring." 



In view of the large amount of sulphate of iron used 

 (over i ton per acre) it was deemed advisable to give a 

 heavy dressing of lime to reduce any remaining in the 

 ground to a harmless state, and i ton per acre of 

 freshly slaked quicklime was evenly applied a week 

 after the last dose of sulphate solution. 



WEEDS ON GRAVEL PATHS AND DRIVES 



Many weeds occur on gravel paths and drives, and 

 are frequently extremely troublesome, Plantains, Dande- 

 lions, Groundsel, Shepherd's Purse, Poa annua, and other 

 plants growing freely in such situations if allowed to do 

 so. The use of the hoe and the knife is very desirable 

 in certain cases, but the eradication of Dandelions, Plan- 

 .tains, and Docks is very difficult by such means. There 

 remain, however, other means of treating paths and 

 drives, namely, by the application of weed-killers, espe- 

 cially after the weeds have been hoed out or cut off. 



Salt is an effective weed-killer if applied in quantity 

 sufficient to whiten the surface, especially when used 

 during hot weather. 



Washing soda may also be applied as a solution, 

 5 Ib. in 10 gallons of water being about the right 

 strength.
