DISEASES OP PLANTS. 353 



crop of eggplants is reported upon, but the yield of fruits was so 

 small that conclusions can not be drawn from the investigation, 



Experi'menU with ctLCimibers (p. 390). — Two varieties of cucumbers 

 are reported upon which were sprayed with the fungicides above men- 

 tioned, in which Bordeaux mixture gave the better results. The effect 

 of soil inoculation, in which soil from an area on which cucumbers had 

 been previousl}^ grown was transferred to the hills, was investigated 

 without any results. 



ExperhnenU vnth lettuce (pp. 390, 391).— Plats of Boston Market 

 and Wonderful lettuce were sprayed with Bordeaux mixture and soda- 

 Bordeaux mixture, 8 applications being given them. The rot was 

 observed in the crown of the Wonderful early in July, and ev(Mi the 

 spraj^ed plants were not wholly exempt from it. At this time the 

 other variety was in bloom and did not show an}' evidence of disease. 

 The leaf spot {Septor'ta lactucm) was somewhat abundant, but, as it did 

 not appear until after the plants had passed the marketable stage, was 

 of little consequence. Inoculation experiments were conducted in 

 which soil from an old lettuce bed was distributed evenly among the 

 open rows in soil that had not previously grown lettuce. The experi- 

 ment demonstrated that the leaf spot can be readily transmitted in 

 this way. 



Experiments with onions (p. 392). — A brief report is given upon 

 experiments with onions groAvn for the third consecuti\'e year on the 

 same soil for the purpose of studying onion smut and other diseases. 

 The crop was nearly a failure, and there was no smut on any of the 

 plants where the disease had been introduced the previous year. 



Experivients ivith heets (pp. 392, 393). — The author investigated the 

 susceptibility of beets to the potato scab and also studied the influence 

 of soil treatment upon its prevalence. The beets were severel}' infested 

 with scab before the roots were large enough for table use. There 

 seemed to be little difference in the susceptibility of the different varie- 

 ties tested. The soil treatment appeared to indicate that the I)est 

 results were obtained from the use of sulphur and then only after it 

 had been in the soil for more than 1 year. 



Experiments vutJi sv)eet corn (pp. 393-395). — Experiments were con- 

 ducted with Black Mexican and Egyptian corn in which cross fertiliz- 

 ation of the 2 varieties was shown. 



ExpifTiments with Sioiss chard and N'ev) Zealand spinach (pp. 395- 

 398). — Experiments are reported with these vegetables in which 

 Bordeaux mixture was used for preventing their diseases, especially 

 in the case of the former. The results obtained were entirely favor- 

 aljle to the use of the fungicide. 



Experiments in winter ridging of the soil (pp. 398-402).^ — Experi- 

 ments are reported in which the effect of ridging the soil during the 

 winter or allowing it to lie flat as shown by the occurrence of various
