the slightest fear but that it will do its work in a thorough manner. But it 
is most important to choose a mild, dull, muggy day, when the ground is wet, 
and to ascertain that the worms are working near the surface before using 
the powder, as it is no use trying to kill worms if they are deep in the 
ground ; it would only be wasting time and money. 
The following interesting photographs were taken during the actual 
operation of cleaning a green :— 
No. i.—A portion of the putting green, taken in the morning, which clearly shows the 
worm casts, and the enormous difficulty there is in licking 18 “wormy” greens into shape every 
morning. 
No. 2.—The men sowing the powder carefully over the surface of the putting green. 
No. 3.—The most important part of the work, watering the powder in. Use as much 
water as possible, so that the powder in solution may quickly run down the holes and get in 
touch with the worms at once. Where water is laid on to the greens, the nozzle of the hose 
should be held as shown in the photograph, pointing straight down, so that the water is forced 
into the worm holes, when it is quite impossible for them to escape. If the water is not laid 
on, fill several tubs or barrels, and place them near to the green, so that the water can be 
applied quickly with pails or cans. Of course, the nearer the worms are to the surface the less 
water is required. 
No. 4.—The worms coming to the surface about 2 or 3 minutes after the powder was 
watered in. 
No. 5.—The same piece of ground about 5 or 10 minutes later. 
No. 6.—One of the three barrow loads of worms taken from the green, a sight that 
must be seen to be believed. 
No. 7.—In my opinion this is the most interesting of them all, especially when taken in 
conjunction with No. 1, as it is the same piece of ground, taken a few days after treatment, but 
now has no worm casts, and is as clean as a new pin, and will only require an occasional light 
rolling to keep it in first class condition, and will be a pleasure to play on, in place of the 
black, muddy surface of former days. 
Apart from the great improvement in the condition of the green, the 
question of labour also comes into consideration, as a green freed from 
worms does not require to be brushed and rolled daily, a distinct saving in 
labour, which might be put to more profitable uses. I strongly recommend 
all greenkeepers, especially inland ones, to give the killer a trial, as I am 
perfectly sure that it will do away with a lot of worry and many complaints; 
and, as things are at some clubs around London and other large towns, the 
players have good reason to grumble when they find the putting greens soft 
and black by reason of the worm casts, when they can so easily be made 
clean and firm.
