Too much heat also has an evil effect , great heat, it is true 

 is necessary to ripen, refine and perfume the grape, but if excessive, 

 and continued, and at a time when the earth is dry, it burns and does 

 not vivify. Its results are similar to those of fall frosts and tempes 

 tuous winds. They are worse felt in the North than in the South, be- 

 cause, in the latter the roots of the plant are much stronger and larger. 



The most favourable season is when the flower opens during a 

 dry, warm, tranquil spell ; when light rains occur frequently to 

 nourish the growing berry; when a regular heat without interval 

 of foggy, muggy weather developes the bunch, and ripens the fruit; 

 and when fair weather presides at the joyous period of the vintage
