The aft'coted tissues were softer than the normal, hut •<till quitr tirin, 

 and there was no juice exudate. In many cases the spots had all 

 the appearance of sunburn or other non-parasitic causes. Fruit so 

 alfeeted soon dropped, unaffected portions turning- a deep red and 

 the whole fruit ultimately munuuifying-. It was noted that the fruit 

 of certain plants remained comparatively free of the disease, while 

 all of the fruit on other plants was affected, the weaker plants ap- 

 parently. Certain fungi were commonly found associated with the 

 spots, in particular ('ladospori)im hcrhanim, Fusarium sp., Pesta- 

 lozzia gnepinia, and Macrosporium sp. Macrosporium sp. is ordi- 

 narily considered the cause of a serious rot of peppers, but in the 

 present instance it was found in so few cases that it is grouped tem- 

 porarily at least with the other forms. Further work is necessary 

 to ascertain the exact relations of these fungi to the disease. This 

 liiay result in the divisio-n of the disease into both parasitic and non- 

 parasitic types as is suggested by observations to date. 



Anthracnose.— In the early stages it was not always possible to 

 distinguish this disease from the above. In general, however, it was 

 marked by more nearly circular areas, often several on one fruit, 

 and more definitely sunken. The spots showed first as water-soaked 

 aieas turning brown. The fruit ripened prematurely, became shriv- 

 eled, but quite often remained hanging to the plant. Two fungi 

 were found in connection with this disease, Gloeosponum piperafnm 

 E. & E. and CoUetotrichum ni(/nim Ells. & Hals., which after further 

 work may prove to be the same, the presence or absence of setae in 

 the fruiting bodies being the only i)oint of difference, which is a 

 doubtful character at best, ^t the tirst report of trouble with fruit 

 rot sju'aying with 3-3-50 Bordeaux was commenced and continued 

 at intervals of a week until eight applications had been made. Counts 

 were made of the diseased and sound fruit at each picking. At no 

 time was it possible to find any constant diff'erence in amount of 

 disease between sprayed and unsprayed areas. The percentage of 

 spotting at first very heavy, gradually declined through the season, 

 due apparently to cultural and climatic reasons; certainly independ- 

 ent of the spraying. 



Wn>T ( SIclfrotiutv Rolfsii Sace). — This common disease of sugar 

 cane (red rot of the leaf-sheath) attacked sev(M'al of the vegetables 

 and was especially serious on the peppi'rs. Plants attacked by this 

 fungus exhibited first a slight drooping of the leaves exactly as 

 occurs when there is a shortage of water. The wilting increased 

 each (hiy with i)artial recovery at night until at the end of four or
