Long-handled jjoultry nets aid greatly in catching the more active ducks. Traps devised from bait seines were found to be prac- tical when birds were concentrated in a relatively small area and could be herded. It is practically impossible to recover the birds which lie on the deep mud flats. All dead birds are removed from the water and thrown up on dry ground so that there will be no further infection from that source. Four-inch flash bombs are used successfully to drive birds from an infected area before they become affected. Rescued birds are taken to hospital pens for treatment. Fresh water and shade are essential for any satisfactory proportion of recov- ery. Using a long glass tube and rubber bulb, each duck is treated with i to -J ounce of 1-5,000 solution of potassium permanganate. In cases where the bird is prostrate, the treatment is repeated three times daily, either with solution or just plain water until the bird is able to drink by itself. Recovery usually takes from four days to two weeks. "When birds are in early stages of the disease, recovery is often very rapid. The bird may be walking around a day or so after being brought to the hospital pens. Death, if such is to be the outcome, is more rapid. A bird which has taken a large amount of toxin may d
