6. Glandular hairs on midrib of young leaflets interspersed with stellate clusters of gray glandless hairs; lateral leaflets ovate to broadly lanceolate, rugose _J. nigra_ 6. Glandular hairs on midrib of young leaflets interspersed with sessile, usually yellow glands; lateral leaflets lanceolate, not rugose _J. honorei_ 5. Midrib of leaflets glabrous or nearly so, sometimes with scattered, sessile glands. 7. Leaflets lanceolate, with acuminate apex; rhachis glabrous. 8. Leaflets widest near middle; vein-islets prominently raised; free ends of veins wanting or if present distinct to the apex and mostly unbranched _J. pyriformis_ 8. Leaflets mostly widest below the middle; vein-islets not prominently raised; free ends of veins slender, terminating in indistinct branches _J. major_ 7. Leaflets ovate or nearly so, with obtuse or acute apex; rhachis somewhat pubescent. 9. Petioles of the 3 lower compound leaves less than 1 cm. long; leaves crowded on a short axis _J. californica_ 9. Petioles of the lower compound leaves from 1+ to 3 cm. long; leaves more distant on an elongated axis _J. hindsii_ Further Tests with Black Walnut Varieties L. H. MACDANIELS _and_ J. E. WILDE, _Cornell University_ In 1937 the Northern Nut Growers Association committee on varieties and judging standards proposed a tentative schedule for the judging and evaluation of black walnut varieties(1). It was pointed out at that time that for one reason or another none of the schedules which had been used in judging walnuts were satisfactory and usable in giving an accurate estimate of the cracking quality and value of a variety. It was recognized also that the schedule proposed was only tentative and that it would need to be modified in the light of future testing and experience. In 1939 the question was again considered(2) and on the basis of tests which had been made, changes were proposed which would make the schedule more realistic. Since then many tests have been made using the modified schedule. The purpose of this paper[A] is to give the data secured in these tests and to consider again the value of the schedule and possibilities of improvement.
