■ 42 Brand of the Cereals [July, 



the action of lime which frees potash from its combination with 

 silica. At least, the use of lime will greatly facilitate this effect. 

 In most soils where, on inspection, slate forms a part in small lami- 

 nae, it is important that the farmer should use lime, for the pur- 

 pose specified above, inasmuch as most of the varieties of argil- 

 laceous slates contain alkalies. 



We hope the numerous analyses which we have made and 

 published in the Journal will serve to direct the attention of farm- 

 ers to the character of the soils and rocks of their respective farms; 

 and when the rocks decompose at the surface, the use of materials 

 furnished ought to be tried as fertilizers in connection with lime. 



BRAND OF THE CEREALS AND BLIGHT IN GRAIN. 



We shall publish in the succeeding numbers the following 

 work — a translation from the German. The following is a con- 

 spectus of its contents, from which it will be seen that it will con- 

 stitute an important addition to our knowledge of the character of 

 the blight in the different species of the cereals. It will contain 

 the full engraved plates of the original on steel.
