DESTRUCTION OF WATER 



WEEDS. 



In considering the question of tlie eradi- 

 cation of water-weeds from ponds, it is neces- 

 sary to draw a distinction between the larger 

 weeds, such as American Water Weed, Water 

 Crowfoot, Duckweed, etc., and the smaller 

 algae.. 



The larger weeds are not only the most ob- 

 noxious, but are also the most difficult to 

 eradicate, as they can only be kept down by 

 cutting and dragging them out. In small 

 shallow ponds this may be done by men 

 wading in the water and using hand-scythes ; 

 or scythe-blades may be attached to ropes, 

 which can be dragged through the weeds 

 from a boat or from opposite banks of the 

 pond. Special weed-cutting saws are also 

 made for this purpose, and several other de- 

 vices exist for use m large stretches of water. 

 Some of these contrivances are of considerable 

 size, and arc very costly. 



The smaller alga; are visible chiefly as a 

 gri>en or brown scum, and are commonly seen 

 during the summer and autumn on still or 

 iicarlv still water. These troublesome growths 

 not only frequently destroy the beauty of 

 ponds entirely for a time, but also have an 

 offensive smell. For the destruction of these 

 >mall, slimy weeds, copper sulphate has 

 proved to Ix^'verv effective, esjMxially m fresh 

 u;iter. Tills iiiaterial lias been used with 

 -,ui( «'s> 111 rtvent vcaiN. both for the smaller 

 iionds at Kew (iai'deiis and for the ornamen- 

 tal water in St. James's Park. Previous to 

 the last two summers, it had V>een a costly 

 and troublesome matter in the latter case 

 to keep liie water presentable in hot weather, 

 men in lixats being employed t<> remove the 

 weed^ with rakes, etc A> a result .il tlie

i.(K>M. without first determnnng by 



in this connection to learn that copper sul- 

 phate applied during the last two summers to 

 the water in St. James's Park was found to 

 be not onlv harmless, but even beneficial to 

 the fish. In former years many had been 

 found to be badly attacked by a fungu.s, but 

 at the last cleaning out the fish were found 

 to be quite free from the fungus disease, and 

 remarkably clean and silvery. 



If there are no fish in the pond, 1 part (by 

 weight) in 1,(X)0,(X)'J (or lib. of copper sulphate 

 to 100,()OU gallons of water) may be applied 

 without rendering the water dangerous lor 



drinking purposes. 



Ordinary commercial copper sulpliate 

 should be used, and, in standing water, may- 

 be easily applied, the only important point 

 being that the copper sulphate must be tho- 

 roughly and rapidly distributed throughout 

 the pond. In small ponds, the copper sul- 

 phate broken small, and enclosed in a bag 

 of loose texture, may be tied to the end ot a 

 pole and drawn backwards and forwards 

 through the water. In large ponds the bag 

 should be towed behind a boat, which should 

 be rowed to and fro in parallel paths not more 

 than from 10 to 20 feet apart. In water with 

 a temperature of about 60 deg. Fabr., some- 

 thing like l(X)lb. of copper sulphate can be so 

 distributed in an hour. The effectiveness of 

 the treatment is found to depend to some 

 extent on the temperature of the water and, 

 if this should be much below 60 deg. Fahr 

 or if the water is very hard, or contains much 

 organic matter, more copper sulphate should 

 be used. It is found that copper sulphate 

 rapidlv disappears from water to which it has 

 been, applied, presumably because it com- 

 bines with the algae which it destroys. Cop- 

 per sulphate has also proved effective when 

 applied to the surface of the sbme m the 

 form of a sprav composed of l^oz. of copper 

 sulphate dissolved in 2 gallons of water; but 

 if water-lilies are present they may be in- 

 iured bv this method of treatment. 



It is necessary to calculate the amount of 

 water in a pond m order to determine the 

 amount of copper sulphate which may safely 

 be applied, and this may be done with siiffi- 

 cient accuracy by multiplying together the 

 average length, breadth, and depth of the 

 pond in feet, and multiplying the result by 

 6i the approximate number of gallons in a 

 cubic foot.-" Journil of the Board of Agri-
