The main work of the year has been on the potato, and the chief problem has been on the determination of the cause of degeneracy.  Incidentally, many varieties have been tested, and the exchange of seed with the Grand Rapids, Crookston and Duluth stations has been started.  If possible, the effect of varying climatic and soil conditions on the potato will be noted.

A few vegetable varieties have been tested and among them the Reading Giant, a rust-proof asparagus, has proved promising.  Malcolm, the earliest Canadian sweet corn, ripened very early and will be tested further.  Washington, a late sweet corn ripening between Crosby and Evergreen, made an exceptionally good showing and may prove of much value for market purposes.  The Alacrity tomato was found to be similar to the Earliana and superior in no way.  Bonny Best and John Baer tomatoes produced smooth, desirable fruit and are deserving of a wide test.

The much advertised “seed tape” was given a trial, and it proved satisfactory in most cases.  For kitchen gardeners who are ignorant of planting distances, methods of planting and varieties, and who can afford to pay a higher price for their seed, the tape may prove of value, that is, if a high grade of seed is maintained.

A CORRECTION.—­In O. W. Moore’s interesting article on “Sexuality in Plants,” which appeared in the November (1915) number of The Horticulturist, two errors were present.  The first is merely typographical, as Kaelreuter’s name, page 411, should be spelled Kolreuter.  The second, however, is misleading, as it states that the process of fertilization is called “Mendel’s Law.”  It is true that Mendel’s Law is based upon fertilization, but it concerns simply the splitting up of certain characters into definite mathematical proportions.  For example, Mendel found that when he crossed a yellow and green pea the first generation produced only yellow peas.  These peas when self-fertilized split up into practically three yellows to one green.  By self-fertilizing the progeny of the second generation it was found that one-third of the yellows bred true for yellow, and two-thirds of the yellows broke up into yellow and green, showing that they were in a heterozygous condition, and that all the greens bred true for green.  At the present time this method of segregation has been proved to hold for many easily differentiated characters in both the animal and plant kingdom, but much more experimental work will have to be done before it can be said to hold for all inheritable characters.—­Prof.  Richard Wellington, University Farm.
