JH is preparing a digest of all double star observations; also comments on sunspot activity.
Has had a letter from Cleveland Abbe inquiring when JH's Catalogue of Double Stars can be expected. Howard and Thomas Grubb have just erected his telescope but the eye end is not finished. Instrument will be very 'handy.'
