My dear Sir/

I have just been glancing over your book on Plant Movements as a preliminary to a more careful & leisurely survey when opportunity offers— I cannot refrain from expressing my admiration of your labors and my great interest in what you say about Root movements— I see you quote Chatin as to the movement of the leaves of Conifers— I have paid a good deal of attention lately to this in several species including some under my own windows & I cannot help thinking Chatin has made a mistake— I always find the white surface exposed in the day time¹

I send you an extract from the Linnean Journal wherein the subject is alluded to but since it was published I have seen the movements in numerous other species but always in the day time.²

I have alluded to the matter in this week’s G. C.³

faithfully y^rs. | Maxwell T. Masters
