WHEAT. 



A notion has always obtained that in England hot 

 summers are productive of fine crops of wheat ; yet in the 

 years 1780 and 1781, though the heat was intense, the 

 wheat was much mildewed, and the crop light. Does not 

 severe heat, while the straw is milky, occasion its juices to 

 exude, which being extravasated, occasion spots, discolour 

 the stems and blades, and injure the health of the plants ]

TRUFFLES. 



August. A truffle-hunter called on us, having in his 

 pocket several large truffles found in this neighbourhood. 

 He says these roots are not to be found in deep woods, but 

 in narrow hedgerows and the skirts of coppices. Some 

 truffles, he informed us, lie two feet within the earth, and 

 some quite on the surface ; the latter, he added, have little 

 or no smell, and are not so easily discovered by the dogs as 

 those that lie deeper, Half-a-crown a pound was the price 

 which he asked for this commodity. Truffles never abound 

 in wet winters and springs. They are in season, in 

 different situations, at least nine months in the year.

TREMELLA NOSTOO. 



Though the weather may have been ever so dry and 

 burning, yet after two or three wet days this jelly-like 

 substance abounds on the walks. WHITE.
