WEEDS IN LAWNS, DRIVES, ETC. 347 



the lawn may be neatly patched with good turves. 

 However, lawns which are overrun with large weeds 

 are best broken up and re-made. 



Removal of Moss. Where Moss occurs on lawns 

 it may be taken as a sign either that draining is 

 necessary or that the soil is poor. The measures 

 necessary to renovate a mossy lawn are: (i) A sound 

 raking or harrowing, to drag out the Moss and open up 

 the surface as much as possible ; (2) the application 

 of a good compost of one part of lime to four of soil, 

 with the addition of a little Peruvian guano ; (3) 

 frequent rolling. In bad cases grass seeds should 

 be sown on the dressing of compost ; the young grass 

 often rapidly overcomes the Moss present ; (4) water- 

 ing with a i per cent solution of sulphate of iron 

 applied through a fine rose, followed by top-dressing 

 as in (2), and if necessary the sowing of seeds. The 

 results of experiments conducted by Der Kgl. Gartner- 

 lehranstalt at Dahlem, and reported in Der Handelsgdrtner 

 (March 13), indicate that a 5 per cent solution of sul- 

 phate of iron is effective in ridding lawns of moss. 

 After the application of the green vitriol solution, the 

 grass should be sprinkled several times with a weak 

 (3 per cent) solution of nitrate of soda. 1 Should such 

 remedial measures not prove satisfactory, draining must 

 be considered. 



Fairy Rings in Lawns, &c. The small fungi which 

 often appear in ring-like patches on grass land may 

 appear in lawns and prove very troublesome. These 

 " fairy rings," as they are termed, expand gradually 

 from the central point where they started, growing year 

 by year in diameter. Messrs. Sutton & Sons state 2 

 that t( One remedy is a dressing of 2 tons of slaked 

 stone lime per acre. Another is basic slag, at the rate
