JDH thanks Asa Gray for sending him some boxes of roots. He has received useful information regarding North American Pines from George Engelmann, whom he wishes would also study American oaks. Mentions: a case of Sikkim Rhododendrons for H. Hunnewell, death of John Torrey, sending Bolander subtropical plants including hardier palms. Some boxes from Gray arrived smashed, some things were lost possibly including the Pinguicula & Chaptalia. JDH owes Charles Sprague Sargent a letter. Ashes are hopeless, the arboretum has been hard work the past winter. JDH will go to France with Thomas Henry Huxley [THH] who has been recommended a holiday for his health.
