Cercospora gosfiypina has been an almost universal accompaniment, ami lias not been 

 second in point of attack, except perhaps in rare cases. In many cases [larallel or 

 immediately succeeding attacks were made by the Collclotnchum. Tije Maaonpo- 

 rium, as a rule, follows closely the attack of the Ceixospora, indeed sometimes seem- 

 ing to be first to attack. In such cases possibly it attacked the spots diseased by 

 Cercospora before the hypha^ and conidia of the latter were developed. The Alto na- 

 na usually succeeds the Macrosporiitm, though often seeming to bo i)arailel with it. 

 By its clusters of hyphie and profusely developed concatenate spores in favorable 

 weather the leaf is soon covered with a mass of spores, giving a blackened aiipearance 

 to the leaves. 



Current theories regarding the cause of the disease are discussed. 

 Experiments with reference to its repression will be conducted at the 

 station.

 and an exhibit of receipts and expenditures for the fiscal year ending 

 June 30, 1890. One hundred and forty-six distinct brands of fertilizers 

 are known to be on sale in the States. The analy.ses of tlic-se and other 

 mannrial substances made at the station in 1890 numbered olO. Analy- 

 sis fees collected during the fiscal year amounted to §4,221.50. The 

 station has material for reports on examinations of seeds, analyses of 

 potatoes, molasses, maple sirup, vinegar, and butter, and a cooperative 

 experiment on the composition of corn grown in dill'erent localities, but 

 lack of funds ]nevents their immediate publication.
