NOTICE. 
It is requested that all communications, addressed to the Society, of 
experiments on land — whether of draining, liming, manuring, or other 
operation — be accompanied with the cost of such operation, with the 
value of the land to rent previous and subsequent thereto, and an 
analysis of the soil upon which such experiments have taken place ; or 
a specimen of the soil, to be analysed by persons employed by the 
Society : it is also further requested that, in communications relative to 
experiments on land in foreign countries, the measures be slated in 
English values. 
Those members who have tried subsoil-ploughing, whether success- 
fully or otherwise, are requested to communicate the result to the 
Secretary, in the hope that, by comparison of the statements, some 
judgment may be arrived at as to the soils and situations which are, or 
are not, suited for this operation.
