The roots had descended the whole length of the poles, and had 
gone into the ground, from which the larger trees now derived nour- 
ishment. In one case, the root had grown so large as to split the 
thick pole on one side from the bottom to the top, and this root pro- 
jected, along the whole length to the ground, about two inches be- 
yond the outer circumference of the pole. Only in an atmosphere 
surcharged with moisture could a seed sprout on the top of a pole, 
twenty feet from the ground, and continue for years to grow almost' 
or quite as well as if it were in the ground. 
At this village he also saw a bush of Lonicera involucrata, which 
was of immense size as compared with what he had seen in Colorado 
and other ]}laces. The plant was growing on a bank and rose 
some ten or twelve feet, when it bent over and rested on the roof of 
the lodge, its numerous branches making a dense arbor under which 
the road passed. The stems near the ground were, some of them, as 
thick as his arm, and the whole plant was covered with very large 
black berries. Subsequently another specimen was noted in the 
woods on a plant of the native hemlock, Abies Mertensiana: In the 
woods the plant is somewhat sarmentaceous. It could not climb a 
hemlock without assistance. This old hemlock was bereft of branches 
to a height of about twenty feet, but the Lonicera was above the lower 
branches, and had journeyed along them to the extremities, beyond 
which it was beautifully in fruit. It could have been there only by 
growing up with the hemlock when that tree was young, and was 
probably of about the same age. 
Butterflies as Botanists. — The caterpillars of Mechanitis, Dircenna^

Ceratinia and Ithonia feed on different species of Solanacea^ {Solanuni 
Cyphomandra, Bassoria, Cestrum)^ those of the allied genus Thyridia 
on Brunfelsia, Now this latter genus of plants had been placed 
unanimously among the Scrophularinere, till quite recently it was 
transferred by Bentham and Hooker to the Solanaceae. Thus it 
appears that butterflies had recognized the true affinity of Brunfehia 
long before botanists did so. There is yet another and more curious 
instance of our butterflies confirming the arrangement of plants in 
Bentham and Hooker's Genera Plantarum. Ageronia and Didonis 
were formerly widely separated by lepidopterists, being even con- 
sidered as constituting distinct families, but now they are to be found 
beside one another among the Nymphalinse, and the structure of 
their caterpillars leaves no doubt about their close affinity. The 
caterpillars of ~^Ageronia feed on Dalechampia^ those of Didonis on 
Tragia. Now these two Euphorbiaceous genera were widely separ- 
ated by Endlicher, who placed the former among the Euphorbiace^e, 
and the latter among the Acalyphece; Bentham and Hooker, on the 
contrary, place them close together in the same subtribe of Pluken- 
etieee, and thus their close affinity, which had been duly appeciated 
by butterflies, has finally been recognized by botanists also.— Fritz
