1 Generally speaking, cereals are more liable to 

 rust 2 than pulses, and among these barley is 

 more liable to it than wheat ; while of barleys some 

 kinds are more liable than others, and most of all, 

 it may be said, the kind called ' Achillean.' More- 

 over the position and character of the land make no 

 small difference in this respect ; for lands which 3 

 are exposed to the wind 4 and elevated are not 

 liable to rust, 5 or less so, while those that lie low 

 and are not exposed to wind are more so. And 

 rust occurs chiefly at the full moon. 6 Again 

 wheat and barley are destroyed by winds, if 

 they are caught by them either when in flower, 

 or when the flower has just fallen and they are 

 weak ; and this applies specially to barley, indeed 

 it occurs when the grain is already ripening, if 

 the winds are violent 7 and last a long time ; for 

 they dry up and parch the grain, which some call 

 being ' wind-bitten.' Also a hot sun after cloudy 

 weather destroys both, and wheat more than barley, 

 so that the ear is not even conspicuous, since it is 

 empty. 



Wheat is also destroyed by grubs ; sometimes they 

 eat the roots, as soon as they appear, 8 sometimes 

 they do their work when by reason of drought the 

 ear cannot be formed 9 ; for at such times the grub 

 is engendered, and eats the haulm as it is becoming 

 unrolled 10 ; it eats right up to the ear and then,
