He distinguishes two categories, viz., dry soils with exfense* culture (culture 

 extensive), and rich soils to which intense culture is applied. He points out that 

 it would be a faulty operation to apply to vineyards situated in garrigiies\ or dry 

 hillsides the same doses of manure as to vines in the plain, in the hope of seeing 

 them produce luxuriant c!ops — it would be a similar case to the frog which wished 

 tr> puff itself out to the size of an ox. It is necessary to endeavour to proportion 

 the dose of manure to the " productive capabilities " of the soil ; capabilities which 

 depend on its depth, on its moisture {fraicheur), and on its intrinsic richness. 



The heavy applications he recommends are to be made annually.

The abo^•e formulae are drawn up on the basis that — ■ 



If we exclude exceptional situations, the worst soils and those which may be 

 classed as without equal, we can admit that the quantities of fertilizing elements 

 to return per acre (reduced to) and per year are as follows : — 



Nitrogen, from 36 to 72 lbs. 

 Phosphoric acid, from 36 to 81 !bs. 

 Potash, from 36 to 90 lbs. 



Professor Lagatu, also of the Montpellier School, has drawn up a 

 very popular wall sheet, in which he gives twelve different formulse ; a 

 heavy and a very heavy, for six different soils, viz., light, heavy, and 

 free ; and for each he considers the case of it being limy or lime free. 



* The French word extensive has a different meaning to the same word in English, and is used, 

 especially in this connexion, as being the contrary of intensive. It may be translated into Knglish by 

 the word " extense " if such an Innovation be permissible. 



t A special form of hillside land with Assured limestone subsoil. 



X The prices are worked out according to latest French price lists. In Australia the cost would be 

 considerably higher.
