18 SCIENCE BULLETIN, No. 12. 



noted that the cow fed on the grass from the affected areas would only "be 

 receiving '26 oz. phosphoric acid and '81 of lirne, and if fed on the grass from 

 non-affected areas, the cow would receive '74 oz. phosphoric acid and 2'43 oz. 

 lime, and the minima necessary to health, according to Stohmann, are 

 1'4 oz. phosphoric acid and 21 oz. lime. 



Further opportunity of examining grasses from affected and non-affected 

 areas did not occur till later, when six samples of herbage were received, 

 four from badly affected areas and two from non-affected areas. These were 

 collected by an officer of the Stock Branch and forwarded for examination, 

 marked Al, A2, Bl, B2, Cl, 02. 



These were submitted to the Government Botanist, who reports as 

 follows : 



Al. Under this number there are three species of grasses, namely, 

 Festuca Iromoides, F. ciliata, and Eragrostis. The latter is too 

 imperfect to work out the species. 

 A2. This contains Festuca bromoides and a tuft of Andropogon sp. 



without flowers. 



Bl. Sorglium plumosum, Festuca Iromoides, and a tuft without flowers. 

 B2. Festuca ciliata, Poa ccespitosa, and tufts of another species with- 

 out flowers. 

 Cl. Festuca myurus, F. ciliata, Bromus mollis, Poa ccespitosa, and 



tufts of a species without flowers. 

 C2. Festuca myurus, F. ciliata, and Poa ccespitosa. 



The samples were submitted to the Biological Branch for examination 

 for fungi. The report furnished is as follows : 

 Al. Ascochyta-like spores present. 

 A2. A few smut spores present. 



Bl. A little smut present on one inflorescence. Fusarium sp. present.; 

 B2. Septoria sp. present. 



Cl. Septoria sp. present, Fusarium sp. present, Ascochyta sp. present. 

 Cz. Spores present, probably those of Spliaeropsis and Fusarium. 



"No fungus parasite was found to be constantly present, and the 

 fungi detected were, for the most part, saprophytic, and such as one 

 might expect to find on almost any pasture." 



The localities from which these samples of grass were obtained are given 

 in the letter of submittal as follows : 



Al. Sample from badly affected country near Bega, following Black 



Eaiige (Gowing, Eodgers, Schuback Bros.). 

 A2 Sample from near Wolumla, very badly affected (Sweeney's to 



Black's " Ayrdale," including Eeids and Eyans). 

 Bl. Taken from Green Brothers, near Bemboka, badly affected. 

 B2. Taken from Pollock's Flat, Bemboka, very badly affected. 

 Cl. Taken from Meringlo and Numbugga, unaffected country; some 



of the best lands recovered from rabbits. 



C2. Taken from the Peak country near Bega, unaffected land; more 

 or less affected with rabbits, and yielding a smaller variety of 

 grasses.
