te tion to functification." I do not know if all observers 

 have seen the Hemileia on the green Cherry. This season 

 I have seen such frequently the whole cluster being cove- 

 red with the efflorescence. In the shade also, the fallen 

 leaves all become perfectly white with the fuller develop- 

 ment of the Fungus and this I suggest should be consider- 

 ed in connection with Mr, Worthington Smith's remarks 

 about Zoospores and robust health of the fungus. 



I have no scientific reputation to lose, and even if I 

 had, I cannot see how I can be blamed for the theory I have 

 adopted after careful perusal of the opinions entertained by 

 scientific investigators in regard to the habits of endophytea 

 of a kindred nature. I have now given my reasons, my 

 authorities, and my justification for the remarks already 

 made and even allowing that through ignorance I have 

 misunderstood all the bearings of the subject I maintain still, 

 that to a coffee planter who grows and cultivates a peren- 

 nial, which lasts for many years it matters little where 

 the germs of a disease or Fungoid parasite enter or origin- 

 ate and that the best thing where a remedy is unknown, is 

 to support the strength and give the plant a chance of 

 withstanding the fury of the attack. We may in many 

 ways modify the constitutional tendency to disease, even if 

 we cannot cure it. It may appear absurd to talk of a 

 parasitic disease being hereditary, but who will doubt that 

 certain peculiarities of constitution may be inherited which 

 although not actually capable of producing the disease may 

 yet have a decidedly predisposing effect ? A planter's policy 

 must be a decidedly vigorous one " Masterly inactivity" 

 means certain ruin and every thing must be done and maintain- 

 ed by the habitual use of experience and prudence. Experi- 

 ence is a progressive accummulation of knowledge derived 

 from trials, use, practice and observation and as such must be 

 Our only guide. With every apology for the analogy I would 

 say I wish what I have written to be the red handkerchief
