The weight of the nut is equally important, since this varies widely in 

 nuts of the same size. Some of the largest varieties are considerably 

 lighter in weight than others in which the nuts are smaller. A desirable 

 nut should be well filled with the plump white meat without too much air 

 space between the shell and the meat. A comparatively heavy shell is 

 more clasirable than a very light one, since the nut is better protected 

 from being crushed in handling and less susceptible to perforation 

 disease, which is one of the most serious troubles of the walnut grower

in recent years. This consists of a non-development of the outer hard 

 layer of the shell. The hard shell is not actually perforated, but rather 

 fails to develop. This disease has become more prevalent in the last few 

 years and affects principally the M^alnut with very thin soft shells, the 

 ones with harder shells not being affected. Nuts that are prone to crack 

 easily and have a fine light shell are more or less injured in handling, 

 thus contaminating the nut. A variety in which the nuts are decidedly 

 uniform is easily distinguished and recognized even by the consumer, 

 and has a marked advantage over one in which the nuts are of all sorts 

 of shapes, so that only an expert could distinguish the variety from 

 others.
