"We were sorry to find that Mr. Burkhill had left Cal- 
cutta to take charge of the Singapore Botanic Garden. Mr. 
Hooper, of the Museum, received me cordially, however, and I 
went through all the mango data they had at the Museum; it 
was not much. I am planning to go down to Poona for a few 
days after we get through here, and I believe there will be 
something to be learned there. 
"It is the wrong season for seeds here now, and I am not 
going to be able to collect nearly as many things as I had ex- 
pected to. I expect to get some interesting things, however, 
down at Saharanpur and over in the Pan jab, and I am also hop- 
ing to be able to bring back with me next spring several 
Wardian cases of plants from here. I have located a number of 
things I would like to obtain for you that can only be had in 
the form of plants. I hope to be able to have these packed 
and forwarded to me at Bombay in the spring, and pick them up 
there, or, if we should not come back that way, have them sent 
over to Bahrein. " 
INDIA. Saharanpur. Mr. A. C. Hartless, Superintendent 
of the Government Botanical Gardens, United Provinces, writes 
October 9th concerning the mango question: "Messrs. Paul and 
Wilson Popenoe have just concluded their visit after spending 
10 days with me. Mr. Wilson Popenoe has had full access to my 
fruit files, especially that of mangos and he, as he says, de- 
rived a large amount of information, and has made very copious 
notes, besides discussing the subject with me and seeing all 
that could be seen in the gardens. 
"To attempt to hunt down the wild progenitor is an hercu- 
lean task. Although some are of the opinion that such does 
exist, others again think that it is extinct. One of my col- 
leagues, Mr. Krumbiegel, Superintendent of the Lalbagh Gar- 
dens, Bangalore, has an opinion that it exists in the Coorg 
mountains, and intends to look for it. 
"I think however that' the question of the number of fer- 
tile stamens is definitely settled. I can find no record of 
other than one stamen to a flower being found. The number of 
stamens to a flower is however of no moment when one considers 
the enormous number of flowers on one tree. I have seen the 
pollen flying in clouds. 
"I do not think that you will find that what is called 
wet regions will have any influence on the pollen, as these 
regions are invariably dry (normally ) at the time of flowering. 
I have seen an enormous crop of flower, completely made unfer- 
tile by rain and mist, or damp easterly wind at the time of 
flowering. What is required to counteract this, is a mixture 
of varieties, whose flowering period would vary. Even a day
