CARAVONICA COTTON. 



By RuNAR Olsson-Seffer. 



Cotton is the most important fiber that enters into the use of 

 mankind today. It occupies more attention in the commercial 

 world than any other product, and we hear on all sides of the 

 great endeavors which are being made to increase its production 

 in those countries which are growing it extensively, as well as to 

 introduce it into new regions. 



There seems to be no doubt, but that the consumption of cotton 

 is increasing at a faster rate than its production. The world, 

 therefore, now needs a new supply of cotton. 



As it is generally accepted that a greater or less scarcity se- 

 riously threatens the cotton mills of this country on account of 

 shortage of tlie raw material, having regard to the possible grave 

 eventualities effected by the cotton pests in the Southern States, 

 the introduction of a new variety should be encouraged. 



ORIGIN. 



• This has been published several times, but we shall briefly draw 

 the reader's attention to this for the benefit of those who have not 

 as yet heard of the tree cotton. 



Ten years ago, Dr. David Thomatis began growing cotton in 

 tropical Australia, and in order to develop a variety suited to 

 the local conditions, he experimented with various forms of cot- 

 ton, until he succeeded in obtaining a very prolific variety, now 

 known as Caravonica cotton. It is a hybrid produced by cross- 

 ing kidney and sea island cottons. The former variety is indige- 

 nous of Mexico, and the latter originated on one of the tributaries 

 of the Upper Amazon. The Mexican variety was chosen for its 

 length, fineness and gloss, the Amazonian for its length and 

 strength. 



The name Caravonica was adapted from the town Caravonica, 

 situated a few miles outside of Cairns, Queensland, where the cot- 

 ton was discovered. The writer had last year, the pleasure of 

 suggesting :x suitable location for a Caravonica cotton colony in 

 Mexico to Dr. Thomatis, who resides in the southern part of 

 ]\Iexico at present.
