were killed and that fruits of older plants did not mature. Studies 

 were made upon the pathological anatomy. Attempts at control 

 with flowers of sulphur and Bordeaux mixture were unsuccessful. 



Between 1894 and 1902 spraying experiments were conducted in 

 New Jersey by Halsted. Success was obtained with Bordeaux 

 and soda Bordeaux mixtures (37, p. 11). Stewart (47, p. 159) in 

 1897 records much damage to cucumbers in New Jersey by anthrac- 

 nose. During the years 1896, 1897, and 1898 Selby (43, 44) studied 

 the disease in Ohio, where great damage was done to muskmelons 

 and to cucumbers grown for pickles. He noted that showers and 

 heavy dews favored the disease and found that a Bordeaux spray 

 checked its spread among muskmelons. In 1894 Garman, of Ken- 

 tucky (22, p. 51), noted anthracnose on melons shipped from the 

 Gulf States and in 1901 gave a brief description of the disease, in the 

 course of which he warns against seed infection. 



Tubeuf in his textbook (53, p. 486-487) states that this fungus is 

 very injurious to seedlings of watermelon, muskmelon, and gourd. 

 He lays emphasis upon the injury to cotyledons and stems. In 

 1904 Eckardt (11) in Germany recommended soaking cucumber 

 seed for one hour in ammoniacal copper carbonate in order to prevent 

 the spread of anthracnose. 



During the years 1901 and 1903 cucumber diseases seem to have 

 become increasingly prevalent in this country. Although downy 

 mildew was probably the main source of loss, anthracnose received 

 added attention, and the more or less purely mycological work of the 

 past began to be supplemented by work of a pathological nature. 



Stone and Smith (49, p. 64) in 1902 reported that anthracnose 

 had been prevalent on muskmelons and watermelons in Massachu- 

 setts in 1899 and that it was also common among greenhouse cucum- 

 bers in 1901. In 1903 Stone (48, p. 35) again briefly described the 

 disease and noted that it occurred early in the season in greenhouses. 

 Clinton, in Connecticut (10, p. 246), reported in 1904 that anthrac- 

 nose was a common and widespread trouble among cucumbers and 

 muskmelons, which recurred annually. The same year, Chester and 

 Smith (9, p. 28) published the results of unsuccessful cross inocula- 

 tions from bean to cucurbits made at Cornell University. These led 

 them to conclude that bean anthracnose is due to a separate and 

 distinct fungus. 



In the same year Sheldon (46, p. 127-137), of West Virginia, pub- 

 lished the results of the most complete study of. this disease that 

 had been made up to that time. Anthracnose was the cause of seri- 

 ous damage to watermelons and muskmelons in that State. He de- 

 scribed the symptoms of the disease, and the morphology of the fungus 

 and made numerous cross inoculations. Among his interesting ob- 

 servations was the fact that anthracnose was more severe on land
