IDAHO QUARANTINES AGAINST PINES 
The State of Idaho issued Quarantine Order No. 8 
under date of March 1st, prohibiting the importation into 
that state of five-leaved pines, currant and gooseberry 
bushes from New Hampshire, Vermont, Massachusetts, 
Connecticut, New York and Pennsylvania. It is ordered 
that quarantine guardians immediately deport or de¬

Plants for High Altitudes 
D. M. Andrews, Boulder, Colorado, proprietor of the 
Roekmont Nurseries, reports a very successful season, 
which contrary to conditions in the east, began early and 
promises to hold on well. Mr. Andrews specializes on 
growing plants native to his own state, which due to the 
varying altitudes has a very rich and interesting flora. 
With noteworthy enterprise he is endeavoring to make 
his nursery a clearing house of information as to the 
trees and plants that are best suited to the different alti¬ 
tudes, by encouraging reports of his customers and others 
that are interested in planting.
