April 6. 1 did not get as far along with this letter 
the other night as l had anticipated, hut l shall try to 
end it now. . 
i was ra.ther successful this season in finding terres¬ 
trial orchids, and there ought to he some good things among 
them. They are rather hard to find, that is, there is not 
much use in hunting for them, hut you stumble on them from 
time to time—if you have good luck. 1 also found some of 
the smallest orchids that l have ever seen. 
Around Tilaran there is a remarkable abundance Ox Tricho- 
pilias, and 1 saw as handsome plants in flower in the woods 
as i have ever seen in cultivation, 'there were also a few 
Oncidiums. 1 do not know why it is, but ± never seem to 
be where uncidiums are when they are in flower. Also, 1 
have never seen a Miltonia in blossom in the forest, although 
l do not believe -they kre rare. . , . 
l wish that l might devise some plan by which it might 
be possible to utilize - native collectors, but l have never 
had’ 1 'any success in that direction. Mr. fowell claims to 
have succeeded, but judging from his accounts, his outlay 
was out of proportion to what he obtained. Over at Santa 
Marla l had several boys bringing in orchid plants, but 1 
managed to accumulate a fine lot of "lirlo del valle { Osmo- 
glossum), and little else. , 
After we returned from Guanacaste to San dose l made 
short trips out on all sides from that place, returning to 
dry the specimens in the Museum. m six weeks spent there 
i got about twice as many numbers of orchids as in the 
previous two months. There are lots of things that I did 
not see upon the trip of two years ago. 
l revisited only one locality at which l collected two 
years ago, El Muneco. l believe that is the richest region 
of all Costa Kica—perhaps not in orchids, i looked for 
S tenorrhynchus standley1 , but couldn't find it. 
We made one trip down to the Atlantic coast, to Cairo, 
altitude about 75 fietfc. On the old cacao trees there 
there was a great variety of orchids, although l imagine 
they are chiefly common things. Mr. Uevermann, with whom 
we stayed, has several species of Vanilla in 
l hrve specimens of one species named for him by bchlechter, 
but 1 do not find the name in our card index of new species, 
fortunately perhaps. J _ 
One trip i made with rrof. Torres to Fraijanes, on the 
slopes of the Volcano of moss. it is a good ™ e ' teT 
than the other parts of the volcano that i know. Valerio 
and I made three trips to the hills of Zurqul, the same
