long, broadly conical in outline, and wine-red when 
fully ripe. They are excellent in quality, and the 
species seems very promising for crossing with our 
northern raspberries to obtain large-fruited forms. 
"Rubus maeroearpus Benth. S.P.I. Nos. 51401, 51706 
and 51764, and R. gleams Benth. S.P.I. Nos. 49332, 49387, 
50691,52302,52717,52733,52734 have been fully treated 
elsewhere (see the Journal of Heredity, vol. 11, No. 
5, May - June, 1920; vol. 12, No. 9, November, 1921) 
and need not be discussed here. It is interesting to 
note that the former is, by our present standards of 
classification, a blackberry in growth and character 
of foliage, but a raspberry in character of fruit, 
while the latter is a raspberry in growth and leaf 
characters and a blackberry in fruit. We have named 
R. maeroearpus , therefore, the 'Colombian berry' (to 
avoid the use of either blackberry or raspberry as 
part of the name) and the latter {R.glaueus) the 'Andes 
berry.'" (Wilson Popenoe.)

Mr. J. P. Rock writes from Kengtung, Burma, Feb- 
ruary 1, 1922: 
"On January 30 I arrived at Kengtung, the capital 
of the southeastern Shan State of the same name. I 
have been out in the mountains since December 30, 
traveling with a Haw-Chinese caravan. This place is 
25 days' journey from Mandalay and a month from Siam. 
I have had a most interesting journey over the moun- 
tains from Chiengmal to Chiengrai , Chiengsen to Hongluk, 
thence to Muang Lin; from there I crossed the mountain 
range between the Meh Len River and the Mekong, des- 
cending into the valley of the mighty Mekong. The river 
bed is very wide but this being the cold season and 
dry, the water was not very high. The bed is full of 
enormous boulders and there are many whirlpools and 
rapids, fine silt and sand in which grows a very in- 
teresting vegetation. The forests are mighty, and I 
must report a fine collection of photographs. On the 
way over I met an English colonel who was going to 
Siam on a tour of boundary inspection. I asked him 
about Chiengtung or Kengtung as it is called up here. 
He said there is one white man who lives there but he 
is now away. 
"This country is full of chestnuts. I think there 
are two species of true Castanea, different from any I
