Ohrdmf, Oct. 5, 1880 



Honored Sir] 



Many thanks for your valued letter which I received on May 28, also the postal 

 wrapped (the requested reprints about American oaks) as well as for the postcard, which 

 you kindly sent from Portland, Oregon, dated August k. After receiving the latter 1 

 waited vainly week after week for the announced shi-oment of galls, until I received a 

 notice from the Post office, Division of De ad letters, dated in Washington September 1^, 

 that the shipment, which is "in excess of weight and measure as unmailable" is laying 

 in Washington. From the post office there I am given the choice of having it sent by 

 express or giving the name of the sender, At the post office here I am told that the 

 minimum Charge for simple packages to Ohrdruf (?) (including duty clearance fees of 

 25 Ibs.) is 5-lA Marks. With such a considerable difference in mailing costs, 1 

 believe I may anticipate your agreement to return the shipment to you and ask you to 

 kindly raake it suitable for sending by letter mail, perhaps by Separation. 



Galls, whose growth embraces 2 or more yearly vegetative-periods, I am familiär 

 with on mushrooms (because then these themselves live as long and have attraction), 

 not however of insects. Sarlier one time I also saw an incidental reference to this 

 difference in a notice (Verh. d Bot. Verein Brandenburg l8?>4 Page 4-3.) From what did 

 you conclude the two year period with these galls? If only according to the living 



larva in them, it could be determined if it is Cacidozvan'or Inquilinae, resp. 



parasites. The latter often still come out of the galls after many years. That the 

 formation of galls Covers more years, appears to me unlikely. 



Hoping that you returned well and refreshed from your trip, I am 



Grate f ul ly yours , 

 Dr, Fr. Thomas
