114 CULTURE OF FARM CROPS. 



(a) 2 parts of water to 1 part of saturated* brine. 



(b) 1 part of water to 1 of saturated brine. 



(c) 1 part of water to 2 of ,, ,, 



(d) Saturated brine. 



No. 6. Washed in sulphate of copper. 



No. 7. Sprinkled but not washed with brine, to which may be 

 added, 



No. 8. Washed with stale urine. 



No. 9. fresh ,, 



No. 10. Washed in chloride of lime and water. Under which 

 head the subdivisions (a) (b) (c) and (d) No. 5, may 

 be used. These also may be used with the sulphate of 

 copper, No. 6 in order to test the utility of different 

 strengths of the mixture. 



Another set of experiments should next be made by se- 

 lecting perfectly clean grains, and infecting them by rub- 

 bing them over with the fungi, obtained from the washing 

 of the different packets of .diseased seeds as above described. 

 This will be class 



No. 11. Rubbed grains with fungus of 



(a) packet F 1. 



(b) packet F 2. 



(c) packet F 3. 



(d) packet F 4. 



Infected seeds should then be washed in pure water to 

 obtain the fungi which will float ; these being put up in 

 packets and numbered. Pure or clean seeds should then 

 be washed in various dressings as below, and then rubbed 

 over with the fungi, as, 



No. 12. Seeds steeped in lime and rubbed with fungus of packet 



No. 2. 



No. 13. Seeds steeped in brine and rubbed ,, ,, 



No. 14. Seeds steeped in sulphate of copper ,, ,, 



The whole of the dressings given in Nos. 1 to 9 

 may be thus used. The experiments last named may be 

 repeated by washing the seeds steeped and rubbed as 

 there described in pure water, in order to remove any of 

 the mixture that may adhere to the surface. Such, some- 

 what differently stated, is an outline of the experiments 



* By saturated brine is meant brine made by dissolving salt in 

 water till the point is reached at which the water will dissolve no 

 more salt this point is called the "point of saturation."
