probably not less than one hundred which differed by one or more 

 characteristics. 



Classification of Varieties. The classification of the upland 

 groups, by Duggar, is here given, with slight modifications in de- 

 scription : 



1. Cluster Type. Plants slender with long basal limbs and 

 extremely short middle and 



upper fruiting limbs; bolls 

 small and tending to grow 

 in clusters; seeds small to 

 medium and thickly covered 

 with fuzz. The plant has a 

 special tendency to drop its 

 fruit. Example : Jackson. 



2. Semicluster Type. 

 Plants with general appear- 

 ance of the cluster type, but 

 with somewhat longer fruit- 

 ing limbs; bolls of various 

 sizes, borne close together 

 but not in clusters; .seeds 

 of various sizes. Example: 

 Hawkins. 



3. Rio Grande Type. 

 Plants with slender, long- 

 jointed limbs; leaves un- 

 usually small with narrow, 

 sharp-pointed lobes ; bolls 

 small to medium; seeds 

 small, dark, smoky-brown, 



and almost without the short fuzz common to other varieties ; pro- 

 portion of lint to seed unusually high 35 to 40 per cent of the 

 weight of the lock-cotton. Example : Peterkin. 



4. Early Type. Plants small, with long, slender, usually crooked 

 fruiting limbs ; basal limbs short or wanting; leaves similar to those 

 of the Rio Grande type ; bolls small ; seeds small and covered with 

 fuzz of different shades; fiber short; blossoms usually marked with
