"FAIRY RINGS"

o THE CIRCLES ON' THE LAWN.. In an article on "L'airy Rings," Mr. A. it. Cockayne, Government Biologist, gives a little advice to lawn owners. He l says( "Su 1 pliate-of-iron solution will in mo3t i cases kill our 'fairy rings/ provided the whole ot tho grounds through which the mycelium of the fungus :s present is thoroughly permeated In many cases, however, the fungus so thoroughly waterproofs the ground that the solution does not penetrate, and is of no use. Good results have been secured by thoroughly forking over tlje ground before applying the sulphate of iron, but in the case of lawns where Iha surface is very hard this is very difficult. In certain cases excellent results have follownt digging c up lawns—without any soil removal— ( and giving several applications of iron v sulphate while the ground is soft and I permeable to the solution. After such T treatment seeding follows. The great a objection to thw practice is that tho |; whole of the lawn having to be treated, j' both cost'and labour ere great. When jj treating tho soil in IMs manner tho c strength of the sulphate should bo lib. v to 2 gallons of water. In certain cases (j aood results have followed the digging- v in of crushed iron sulphate at the rate of sowt. per acire, but in general better results follow tho dissolving of the material in water."
