eveiy grain looked as if it had been dressed with soot. The grain 

 was sent out immediately aftei-wards for sowing. 



At Dookie the sowing took place in June, and the seed-bed 

 was a moist one. The rainfall for April was "25 in. ; for May, 1'99 in. ; 

 and for June, 4'36 in. The bunted gi'ain sown in a moist seed-bed wa« 

 particularly liable to infection. 



At Longerenong the seed was sown on 1st June, and the seed-bed 

 was linn, moist, and in good condition. The rainfall for Api^l was 

 '9in. ; for May, 3"22in. ; and for June, 2'55 in. The mean tempera- 

 tures for May and June were 50 deg. Fahr. and 45 deg. Fahr. 

 respectively. 



At Burnley the plots were sown on 16th June in I'ather a loose 

 seed-bed, the soil being a sandy loam. The rainfall for April was 

 '33 in.; for May, '87 in. ; and for June, 3 '94: in. The mean tempera- 

 tures for May and June Avere 54 deg. Fahr. and 50 deg. Fahr. re- 

 spectively. 



Since the weather conditions exercise an important influence on 

 the germination of the spores, it may be noted generally for the first 

 quarter of the year that the rainfall was scarcely 50 per cent, of the 

 average amount, and this was followed by one of the driest April 

 months ever known. The breaking-up of the drought occurred in 

 May, and the rains in June were above the average, so that altogether 

 the conditions were favourable for the germination of the spores and 

 the seed wheat at the same time. The results' of the experiments have 

 been carefully tabulated, and while they show that Florence ihay have 

 as much as 12 per cent, of stinking smut, and Genoa 22 per cent., yet 

 on the whole they were remarkably resistant. In one plot Genoa was 

 absolutely free, and in others both varieties had only 1 per cent.
