CHESTNUT BARK DISEASE. 375 



inferior in flavor to the European varieties, such as Paragon, 

 the Japanese is already grown on a large scale as a nut-pro- 

 ducing tree. There are, however, many trade varieties of 

 dubious origin. Some of these may prove later to be subject 

 to the disease." 



So far as the writer has observed in Connecticut, the 

 Japanese varieties seem to have more or less resistance to the 

 disease, but our experience has not been very extended. We 

 have seen two cases, one in a nursery and another in a private 

 yard, where the Japanese species was directly attacked by the 

 blight, but have examined it in nurseries several times with- 

 out rinding any sign of the disease. We also failed to produce 

 the disease in a Japanese variety in the Station yard, although 

 the bark was inoculated in sixteen different places. 



In April, 1910, with the aid of the State Forester, we had 

 set on the hillside, beside a badly diseased patch of chestnut 

 timber on the Whittemore estate in Middlebury, six young 

 trees each of the following varieties: Paragon, Reliance, Early 

 Bon, Japan Mammoth, Late Tamba and Alpha, mostly Japanese 

 varieties. These were planted to see if any would escape the 

 blight. Unfortunately, many of them were killed back to the 

 ground the first summer by drought. On the stems of some 

 there appeared on the exposed southern side sun-scald cankers 

 similar to those described by Powell, but no sign of the blight 

 fungus showed that year. Since then a number of the trees 

 have died from drought, but none have been killed or seriously 

 injured by the blight fungus, though in 1911 a little of the 

 fungus was found on two of the badly injured Japanese Mam- 

 moth, and in 1912 on two of the languishing Paragon trees 

 cankers had started. The Paragon, of all the varieties, stood 

 the transplanting and drought conditions the best. 



Some years ago, through the work of the late Judge Coe 

 of Meriden, Mr. Hale of Glastonbury, and Dr. Britton of this 

 Station, considerable interest was aroused in the cultivation of 

 chestnuts, especially the large fruiting varieties. While we 

 know of no cultivated orchards that were set out, a number 

 of men grafted these varieties onto the native sprouts and 

 trees. Among these were W. O. Corning of Marbledale, and 

 Mr. John Dickerman of Mount Carmel. Both these gentle- 

 men say their grafted trees have been badly injured by the
