nor are cattle or sheep that may be allowed 

 to graze on it. 



"The best times to treat greens are early 

 in spring or in the fall, when the ground is 

 soft and the worms are 'working.' They 

 are then nearer the surface and ' rise ' much 

 more readily than when the ground is harder, 

 when more of the mixture is required. 



"If a green is treated in the spring com- 

 paratively few worms will be in evidence in 

 the fall. But if any are left it is better 

 economy to get rid of them. Unless their 

 'casts' are removed before the green is cut 

 or rolled it means the final ruination of the 

 green. The labour and consequent expense 

 involved in first brushing off the 'casts' 

 represents a big item, and it is better economy 

 to get rid of the pest at the outset." 



It may be added that since Mr. Travis 

 wrote the above, trials of other grasses have 

 been made, with the result that the fipe- 

 leaved fescue is being used now in con- 

 junction vi^ith the bents. The crested dogs- 

 tail, which makes a very low turf, with very 

 firm leaves, and stands hard usage, will often 

 be found a good grass for a putting-green, 

 and may be used as indicated on page 104.
