in enhancing the value of this already important collection by co - 
lecting themselves, especially during the coming winter and S|wing, 
and bv asking friends away from the city to collect and tor- 
ward specimens of all kinds of plants. The specimens fiom out

case we wish to discover and record the range and distiibution 
of the plants native to our State.
