The year has witnessed, with the co-operation of the Academy, the 
completion of a treatise on the Phanerogamic Flora of the State, giving 
the range of nearly 1,500 species, together with specific studies of forests, 
weeds, and unutilized vegetable resources; this now is awaiting publica- 
tion. 
The year has also seen the culmination of extensive investigations 
upon beet sugar as a possible Indiana product and the determination of 
large areas—practically the whole of the northern part of the State— 
where under existing conditions the sugar beet can be cultivated with 
profit. Plant disease, like the San José scale on fruit trees or smut on 
cereals, have received much attention, and valuable results have been ob- 
tained. Valuable conclusions have been reached in the use of specific 
fertilizers for specific plants, and upon the relative merits of surface and 
sub-irrigation. 
Yeast investigations haye been continued and further conclusions 
reached of prime importance to every household. * 
Additions have been made to our knowledge of cell life and cell modi- 
fication in plants, as affecting various theories of heredity, and much 
systematic work has been prosecuted in yarious parts of the State tending 
to perfect our knowledge of the State flora. Our denuded lands and their 
possible reforestration have received scientific attention. 
In zoblogy the greatest event of the year has been the issuance from 
the State Geologist’s office of a monograph upon the birds of Indiana. 
This work is thoroughly up to date and is not a mere catalogue. It gives 
attention to the economic side of bird life, and enables the farmer to 
recognize his friends and enemies. No recent extensive scientific publica- 
tion in the State has created such a widespread interest. An edition of 
8,000 has been already exhausted and the demand is for more. 
An event of almost equal importance is the removal of the Summer 
Biological Laboratory from Turkey to Eagle Lake. At the former loca- 
tion many Indiana teachers and scientific workers have been trained in 
laboratory methods; many more will find their way to the new location 
and through its influence will enter the ranks of trained specialists. In 
addition to this, much light is being thrown upon the problem of variation 
as bearing on the origin of species. During the year there must be cred- 
ited to Indiana some first-class work on cave fauna which is receiving 
national attention, and which must have a large bearing upon the prob- 
lem of the influence of environment.
