to be the standard of excellence, and is a good keeper 

 though yielding very lightly. 



The market it is intended to supply should, therefore, 

 be specially planted for. If for northern shipment, the 

 Jersey Sweet is preferable. For early local sale Orleans 

 Red ("Nigger-killer"), Early Golden or Bermuda Red, 

 head the list. For winter storage and local market in 

 spring it is best to rely on the good old popular standard 

 — the Georgia Yara-despite its light yield, or rein- 

 force it with Vineless, which closely approaches it in 

 quality and is a much heavier cropper.

SYMBIOSIS is the intimate :,sx,,riai i..,, ,,t two or 

 lore distinct organisms, with iM-ntiit t" t-nt- only, or to 

 isalism; consortisni; copartnership. In 

 h organism is called a symbiont. 



According to the character of the union, several kinds 

 of symbiosis have been recognized: (1) Mutual antago- 

 nisth- vvniliioM- ' hiiilual parasitism), when two organ- 

 ism^ : ! . : li <.ther, as certain bacteria and ani- 

 ninN. ;i i : ' . iiig a "natural resistance;"also the 



synir. :.i-.ii . I ..:, i ,,, lichens with lichens. (2) Antago- 

 nistic - . iiii'j''-i- liiiie parasitism), when the host is 

 partlv ■•r i |i|n(|y killed by the parasite, as the po- 

 tato aiiM til.- r.it fuiiLTUS {Phytophthora infestans): or 

 galls iliiiiiriirophi. s) produced on the host as in the 

 black knot ..( plums; and in higher plants, which live 

 at the expense of others, as the mistletoe (i^rnnl and 

 the dodder (chlorophylless). (.IIMutual syml.i.i^is.wlu n 

 there is often reciprocal advantage; I'M iinl li.i-ni, 

 when one symbiont nourishes the other witlniut ;i]i- 

 parently receiving any return, as the mycorrbiza and 

 the roots of forest trees; (b) mutualism, when a mu- 

 tual benefit results from the union of two organisms 

 capable of living separately, as the bacteroid and the 

 roots of the Leguminosfe; (c) individualism, when the
