BESTJLTS OF THE JOURNEY 95 



And on the 6th : 



I really believe that the Moraines are the only points in 

 my journey worth much ; except the negative results of 

 no Alpines on the Atlas ! 



Darwin, who published his ' Expression of the Emotions 

 in Man and Animals ' in 1872, had asked him to make obser- 

 vations on this point among the Moors and Berbers. The same 

 letter adds : 



I tried for expression, but the people are too civilised, 

 and so taciturn and unpleasant with Christians, that their 

 features were too constrained to make anything out of. 



Before long, however, the book of Moorish travel was brought 

 to a standstill. He writes to Ball on September 17, 1871 : 



In primis I wanted to tell you, that I see no prospects of 

 my publishing my book on Marocco within any reasonable 

 time, and I therefore hope you may publish whenever and 

 wherever you choose at home and abroad. I have a little 

 narrative on the stocks. I had begun and made progress 

 with it, but have been worried out of my life with Ayrton, 

 Gen. Plant. and Fk>ra Indica, and in my mother's state 

 of health I cannot count on finishing it for some months. 



The Marocco plants I have all ticketed and thrown 

 roughly into species; 



I should still like to join you in a work on Marocco Botany 

 in any shape you please, and take any of the drudgery. 



Later, the additional duties as President of the Eoyal Society 

 still more emphatically blocked the way, and the book was 

 ultimately brought out by Ball in 1878, using Hooker's journal 

 and fragment of narrative as well as his own and Maw's 

 journal. Hooker also contributed three botanical appendices, 

 on some economic plants of Marocco and comparisons of the 

 Marocco Flora with those of the Canaries and of Tropical 

 Africa. Ball's general description of Marocco Botany has 

 already been mentioned. 



The following letter on social economics also arises out of 

 the Marocco experiences.
