THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 243 
cumstances deferred this journey until late in October—so that 
vegetation was entirely gone. 
Do me the favor to enquire of Mr. Halsey concerning the 
arrival of my package, which left Easton on the 31st March—& 
I advised him thereof by letter & permit me once more to beg you 
& him, to try to do something for me. Knowing, however by my 
own experience how difficult that is—when duties occupy so great

of your power. Within a few weeks I expect to go to Philadelphia 
—if possible I should be very glad to become acquainted with

Excuse these hasty lines, designed only to express to you my 
extreme joy at your resuscitation—after so long a silence—& my 
warm desire to participate in the plans you propose. Believe me 
Yours most sincerely

the Tuckerton Stage early the next morning, and arrive at the 
Bridge in time to collect many plants before night. I must re- 
turn to Phil. early enough to take the steamboat for Trenton 
on the 2oth, for I am engaged to give a short course of chemical 
lectures at Princeton College, which will commence on the 21st 
inst. There will not be many rare plants to find in the pines— 
but if we only found one it would be worth while to go. 
Ever since our lectures closed at the Med{[ica]l College (March 
Ist last) I have been occupied in arranging my herb”. It was 
necessary to put my materials in order before sitting down to 
write the continuation of my Flora [89], and I have hardly made
