S. W. Tredway, of the above company, wrote on September 17,1904, as follows: We have applied sulphate of copper twice, putting same in a bag at a time when our pond was still and dragging it all around. We used 3 pounds of copper with each treatment. We have not been running hot water into the pond for some three or four weeks because of the fact that our condenser gave out, and we are now installing a new one, and consequently there has been no current through the pond during all this time. The copper has completely removed the odor arising from the pond, and there is no question but that the growth has been checked, and from appearances we should think that the weeds are commencing to die o'ff. We probably will not be in a position to say definitely just what the results are before next spring. We are going to make an effort in the early spring to prevent a new growth entirely. NECESSITY FOR DETERMINING THE POLLUTING ORGANISM. Before the quantity of copper required in a particular reservoir can possibly be determined it is absolutely necessary to ascertain the exact character of the organism causing the trouble. This makes a microscopical examination of the first importance. Also, the earlier in its development the presence of the polluting form is revealed, the more effective will be the treatment. If examinations are made at short intervals throughout the year, the first appearance of the troublesome alga? can be noted, and by treating promptly at the first sign of their decided increase it is possible to destroy them bef...
