Bear Fernald: 
I have your letter of February 3. At present I am planning 
to see you before noon on Iriday unless something unforeseen 
prevents my getting away from Providence that day. I shall be 
very glad to do what I can to help you and Dr. Robinson in handling 
the new apparatus, tut I do not know how much this will be as some 
of the different makes I know absolutely nothing about,beyond 
general fundamentals. I would be glad if you would write me, by 
return mail if possible, and give rne a little information as to 
the make of the apparatus and at least a crude diagram of it. 
Possibly you may have a circular showing an illustration of it. I 
speak of this merely because I may have some special directions 
here that I could look over a little before seeing you. 
Just at present I find it is impossible to say whether I shall 
be able to stay over night or not, but I hope so, in which case 
I should be glad to avail myself of your kind invitation. I have 
teen planning definitely to look over the cryptogamic collection 
in the Club Herbarium that day, and go to the meeting Friday night, 
so there will be no inconvenience added to my present plans. if 
I know before Friday morning that it will be possible to stay 
over night Friday, I will drop you a line Thursday night. 
Sincerely
