The subject on which I am to talk is rather difficult to present at this time, but I will mention a few of the most promising new varieties.

The new and valuable hardy raspberry No. 4, growing at State Fruit-Breeding Farm.

We have developed several hundred new varieties of fruit since we started fruit-breeding at the State Fruit Farm. Many of them are very promising, but it probably will take several years before we really know what we have that will be of value to the public.

We have been growing thousands of seedlings of apples, plums, grapes, raspberries, strawberries, gooseberries and currants, from which valuable varieties have been selected. All of them have been put under propagation in a small way for testing at the Fruit Farm, trial stations and many other places. Some very favorable reports from several places have been received during the last year from parties who have fruited these new creations. We also have some hybrid peach and apricot seedlings which have stood the test of the last two winters. Some of them blossomed very freely last spring, but on account of the hard freeze in May they did not set any fruit. I hope to be able to report on these another year.

Hybrid plum No. 21—at Minnesota State Fruit-Breeding Farm.

The results of breeding strawberries have given us one everbearing and one June-bearing variety, which have been tested in many places throughout the state. The June-bearing variety has been introduced as Minnesota No. 3. The berries are almost identical with Senator Dunlap in color and shape, but somewhat larger and, I think, more productive. The plants are equal to Dunlap in hardiness, or more so, a stronger plant, and a good plant-maker. The fruiting season is about a week earlier than Dunlap. It is a firm berry and stands shipping a long distance. My belief is that this variety will make one of the best commercial berries for the Northwest.

The everbearing variety is known as No. 1017. It is a large, round berry, dark red color, and is of the best quality. This variety is strong and vigorous and a good plant-maker when blossoms are picked off early in the season. It is also very productive. The blossoms and berries on a number of plants were counted in October, and we found all the way from 200 to 345 berries and blossoms on single plants. This is, of course, a little more than the average, but it shows what it will do under ordinary conditions. This variety has been growing next to Progressive, on the same soil, with the same cultivation, and I think that persons who have seen it this summer will agree with me that it is far ahead of Progressive in size and productiveness. I will say right here, if you expect to have a good crop of fruit in the fall, keep the most of the runners off. If you encourage them to make runners, or plants, you will have less fruit.

The raspberries sent out as Nos. 1, 2, 3, 4, 5, 6 and 7, are all worthy of trial. The No. 4 has fruited several years and gave the best showing so far. The fruit resembles the Marlboro somewhat, but the color is darker. It is not one of very high quality, but the size of the berry and its appearance will more then make up for this. The canes and foliage are generally healthy and very hardy. This variety will be planted very extensively just as soon as enough stock can be supplied to fruit growers.

The Burbank crossed with Wolf, hybrid plums. There have been several of these sent out to trial stations, and as premiums to members of the Horticultural Society. I will mention them in order as to size of fruit. No. 5, 12, 4, and 6 will measure 1–¾ inch in diameter. Nos. 21, 10, 17, 9, and No. 1 are nearly as large. The kinds which have given best all around satisfaction up to the present time, are Nos. 1, 6, 9, 10, 12, 17, 21 and 25. One or two years more trial should give us an idea which ones will be worthy of general propagation.

There are also several varieties of Abundance and Wolf crosses which have fruited for several years. The quality of the fruit of these hybrids is probably somewhat better than the Burbank and Wolf hybrids, but the fruit in most cases runs smaller. No. 35 is probably one of the best; its fruit is about 1–½ inch in diameter, colors up all over before it is ripe, and will stand shipping a long distance, as they can be picked quite green and still are colored up all over. There are several numbers equally, or nearly, as promising as No. 35.

Sand cherry X Satsuma plum No. 145 is in the same class as Sapa. The color of the fruit is bluish black when ripe, the flesh purple, pit small and nearly freestone; fruit ripens first part of August. This tree is a strong grower and makes a large tree. We also have another plum, Compass cherry X Climax, about the only variety which fruited this year. The color of the skin is almost blue when fully ripe; the meat is green and of a very pleasant flavor. The pit is small and clingstone; size of fruit is about 1–½ inches in diameter. The tree is a strong, upright grower. This variety has been propagated this summer. I will not try to describe any more as there are some 2,000 hybrid plums on the place and only a small per cent have fruited.

Ornamental Purple Leaf Plum, originated at State Fruit-Breeding Farm.

In grapes we have several varieties worthy of propagation, but I will just mention two varieties. One is a red grape about the size of Wyoming Red. The bunches are large and very compact; the season for ripening is about with Moore's Early; the quality is good enough to make it a table grape. The vine is just as hardy as Beta grape, of which it is a seedling. It has good foliage and the vine is a rank grower. The other variety is black when ripe, nearly as large as Moore's Early. The fruit is ripe first part of August; the vine is vigorous and hardy.

Strawberries and raspberries were a good crop this year, but all other fruit was a total failure on account of the killing frost and snowstorm on May 18th. Apples were in full bloom at the time, and a good crop of plums had set on the trees, but all fell off a few days later. There were no currants or gooseberries and only a few grapes.

Mr. Waldron: What do you think the male parent was of the red grape?

Mr. Haralson: I couldn't say. We don't know what the cross is.

Mr. Waldron: Did you have any red grapes growing there?

Mr. Haralson: I presume there were quite a number of varieties growing near by. In the Beta seedlings we find a number of grapes that ripen green and also some black and a number red, but not a great many, I would say from five to seven per cent of the seedlings.

Mr. Wellington: Have you been able to cross the European plum with the Japanese?

Mr. Haralson: We have one or two varieties, but the fruit is very small, the fruit isn't very much larger than the Compass cherry. The tree is a very strong grower and makes a large tree, but the fruit is not up to what it should be.

Mr. Cook: What number do you hold that red grape under?

Mr. Haralson: The red grape is No. 1.

Mr. Sauter: Which is the next best raspberry besides the No. 4?

Mr. Haralson: I couldn't tell you at present. I thought the No. 2, but from reports I have had from several places some think No. 1 is better. No. 4 is the best of them all so far.

A Member: I would like to ask which of those raspberries is the best quality.

Mr. Haralson: They run very much the same, very little difference in the quality. The quality I should say compares very favorably with the King.

The President: Those of you who know of the wonderful work done by Mr. Haralson can not help but say, "Well done, good and faithful servant." He has surely accomplished wonderful results out there, and the people of this state and adjoining states will all in time enjoy the fruits of his labor. (Applause.)

Kill Wild Onions in November.—The secret of the vitality of the wild onion lies in the two sorts of underground bulbs. Each plant produces one large bulb, which germinates in the fall, and four or five small ones, which start growth in the spring.

Late fall plowing, followed by early spring plowing and planting the infested land to some clean cultivated crop destroys the wild onion pest by killing both sorts of bulbs as the growth from them appears and before they have a chance to multiply. The fall plowing should be deep, and care should be taken to completely bury all green tops of the onion. If very much top growth has been made, a harrow run before the plow will facilitate the thorough covering of the tops.

Another interesting and valuable point about the wild onion is that the spring bulbs rarely produce heads; consequently, if the infested land is plowed in the fall, a spring oat crop practically free of onions can always be secured. But for complete eradication of the onion, both fall and spring plowing is necessary, and November is the best time to do the fall work.
