4:2 RUST AND MILDEW IN 



1888* Humidity excessive in January and February, but 

 deficient in the remaining months ; cloud was on the whole defi- 

 cient; rain was excessive in January, but thereafter on the whole 

 deficient. Conditions in January very favourable to the fungus, and 

 generally they were favourable to the host. Outturn fell slightly. 



Punjab. 



1875. No data for humidity and cloud ; rain deficient through- 

 out. Condition unfavourable to the fungus. Outturn rose. 



1876. Humidity deficient, except in March ; no data for cloud ; 

 rain on the whole about normal. Conditions favourable to host, 

 and possibly also to the parasite. Outturn rose slightly. 



1877* Humidity excessive ; cloud excessive, especially in 

 January and April; rain excessive (especially in February), except 

 in March. Conditions apparently favourable to host, but especially 

 to fungus. Outturn fell somewhat, and this may be attributed in 

 great part to the parasite, as otherwise the outturn should have 

 been greater than in the previous year. 



1878. Humidity in January, February and April excessive, 

 but very deficient in March ; cloud excessive in February and 

 April ; rain excessive in February and April, but deficient in 

 January, and especially March. Conditions appear to be very 

 favourable to the host and to the fungus, especially in February. 

 Outturn fell considerably. 



1879. Humidity deficient in all months, especially in January 

 and April ; cloud normal in January, deficient in February, 

 excessive in March, and deficient in April ; rain deficient in all 

 months, except March. Conditions fairly favourable to the host, 

 but excessive cloud and rain in March decidedly favourable to the 

 parasite. Outturn fell considerably. 



1880. Humidity on the whole about normal for the first three 

 months ; cloud deficient, except in February, when it was ex- 

 cessive ; rain deficient throughout, except in February, when it was 

 normal. Conditions fairly favourable to the host, and excessive 

 cloud with normal rain in February favourable to the fungus. 

 Outturn only slightly better than in the previous year. 



1881. Humidity deficient in January and February, and ex- 

 cessive in March and April ; cloud much deficient in January, but 

 excessive in February, March and April ; rain deficient in January 

 and February, excessive in March, and normal in April. Conditions 

 very favourable to both host and parasite. Outturn only sightly 

 improved, equal to that of 1878. 



1882. Humidity excessive in January and February, deficient 

 thereafter ; cloud excessive in January, deficient in February and 

 [March, and about normal in April ; rain excessive in January, 

 deficient in February and March, and somewhat excessive in April. 

 Conditions not favourable to the fungus, especially the absence of 

 cloud in February and March, and the same rainfall. Outturn rose 

 slightly. 



1883. Humidity on the whole above the average; cloud
