To the list of birds must be added the record of the deaths of four cottontails and on unfortunate tree-toad. The above record of birds taken sho-vvs that one bird was killed for every 100 trees fumigated, or approximately one bird to the acre. In considering game birds alone the ratio becomes one to 200, or one game bird to two acres. When the number of birds which probably spend the night in an orange grove is considered, the death rate is not very large. These results would seem to lead to the conclusion that the problem is not yet a really serious one especially when the importance of the fumigation work is Fig. 35. Birds killed by fumigation : Six quail, seven doves, thirteen linnets, seven moclcing-birds. Photo by E. C. Vail, July 29, 1930. A perusal of the notes taken by the investigating deputy reveals the fact that nearly all of the birds killed were, at the most, half grown, some being destroyed in the nest. ]\Iost of the adults seemed able to leave the cover as the ''tent" was being pulled over. Here, we have another interesting fact. In those trees which w^ere of a relatively small size bird mortality was the greatest because, due to the size of the trees, the time requirecl to "pull" the canvas was short. In the older groves, where the trees were larger, the extra time required in setting the correspondingly larger tents gave the birds an opportunity to make their escape. Still another point to be noted is the disposition of mem- bers of the crew\ Some men, hearing a bird strike the inside
