(48) When collecting walnuts I obtained a lot of nuts from a correspondent from the Mogollon Mountains in Arizona. The nut resembles that of _Juglans rupestris_, but is larger and thicker shelled. No one knows whether it is an undescribed species or only a distinct variety of _Juglans rupestris_. Several of the nuts sprouted, but various accidents happened to them and this tree now, seven years old, is the only one of the lot living. It looks very different from any American walnut I have ever seen. In fact, it looks so much like a stunted heart nut that I suspected that one of these nuts might have gotten into the lot by accident. In digging down about the stem, however, I found only the shells of a Mogollon walnut. We can not tell what the tree will bring forth, as it is not bearing as yet. (49) Two groups of chestnut trees of the McFarland variety, about eighteen years of age. They grow and blight and bear, but have not blighted to the point of killing altogether. They have been neglected because the nut has not much value. (50) A group of Merribrooke hazels. Some years ago I devoted several weeks to examining hundreds of hazel bushes in this part of the country, where they are a pest, and I also visited other hazel localities at a distance. Among all the bushes examined the best nut was found on my own property and I learned later that this particular bush had been known among the boys of the locality for a century. The nut is of large size for an American hazel, thin shelled, of high quality. This group consists of transplants of root progeny from the parent bush. (51) A Horn hazel (_Corylus cornuta_, commonly wrongly designated as _Corylus rostrata_). A species fairly abundant in Connecticut, and I transplanted these bushes because they happened to have a tremendously long involucre. The nut of the horn hazel is not of such good quality as that of the common American hazel, and I have not succeeded in making hybrids between this and other hazels as yet. The hazels are very ancient in descent and each species likes to retain particular identity. (52) A number of stocks of red birch, white birch and scrub oak grafted with European hazels and chinkapins, but the grafts all died. The grafting was done as an experiment in the hope that we might possibly utilize our waste lands which are covered with birch and scrub oak by grafting these trees with hazels and chinkapins. Some of the grafts lived for such a long time and put out such long shoots that the experiment will be tried again next year. It would not seem worth while, excepting for the fact that it was a bad spring for grafting anyway, and hazels did not even catch on hazels, though they caught freely last year. The Japanese do grafting on stocks widely different from the scions, but we have not developed that particular feature in this country as yet.
