A severe and fatal outbreak of Aspergillosis was reported from several places in the Central Provinces.
Young birds are most liable to an acute infection, but the older individuals are more resistant.
Symptoms of the disease are given.
Aspergillus fumigatus has been isolated from the heart and cutaneous blood, lungs and other organs of sick birds, eggs and poultry feed.
A detailed microscopic study of the organism is given.
Besides fowls the fungus has been found pathogenic to human beings, goats and rats.
Eggs from sick birds hardly ever hatched out andAspergillus fumigatus has been isolated from most of them.

An experiment is described in which dry method and wet method of planting sugarcane have been discussed.
The seasonal cycles of individual constituents of cane were included in order to determine if any marked differences exist and could be associated with particular method of planting.
The experiment was laid out at the Government Demonstration Farm, Bilaspur, during 1936–40 and data regarding cultivation, general growth and crop yields were recorded. Samples of whole cane were collected at fortnightly intervals from November-April for all the five years and analysed by the staff of the Chemistry Section of Department of Agriculture, Central Provinces and Berar.
The cultural observations made were germination, number of weedings, number of irrigations, tillering, yield of cane and gur, cost of cultivation and net profit. The chemical data collected was weight of individual cane, percentage of juice in cane, percentage of sucrose, invert sugar, total sugar in juice and sucrose-invert sugar ratio.
The cultural observations showed that dry method of planting was more economic and profitable than wet method of planting sugarcane.
The chemical data did not exhibit any difference in the composition of the cane grown by two methods.
The chief constituents determined were found to exhibit definite seasonal cycles and are of importance in diagnosing the practical problems concerning gur and sugar making.
The sucrose and invert sugar contents show a very high negative correlation showing transformation from one to the other form. Wider sucrose-invert sugar ratio is more favourable for gur and sugar making.
