Part 2 — Notes to Chapter XV.
Reading edition
On the dissemination of fungi, the reader will find Fulton, "Dispersal of the Spores of Fungi by the Agency of Insects," Ann. Bot., Vol. III., 1889, p. 207, and Sturgis, "On Some Aspects of Vegetable Pathology and the Conditions which Influence the Dissemination of Plant Diseases," Botanical Gazette, Vol. XXV., 1898, p. 187, both useful papers. Further information will be found in Zopf, Die Pilze, Breslau, 1890, pp. 79-95 and 228, and Wagner, "Ueber die Verbreitung der Pilze durch Schnecken," in Zeitschr. f. Pflanzen Krankh., 1896, p. 144. The estimates as to losses due to epidemics are taken from Watt, Agricultural Ledger, Calcutta, 1895, p. 71; Balfour, The Agricultural Pests of India, London, 1887, pp. 13-15; Eriksson and Henning, Die Getreideroste; the publications of the U.S. Department of Agriculture, The Kew Bulletin, and elsewhere. The reader will find further examples in Massee, Text-Book of Plant Diseases, 1899, pp. 47-51. Both these subjects are well worth further attention, and I know of no complete account of them.
