unless this be so, the weed cover crop must in a short time 
lose its source of seeding and become a thing of the past. 
At the very best, a cover crop of weeds is an uncertain 
thing.

POLLINATION STUDIES IN DEPARTMENT OF HORTI¬ 
CULTURE OF THE OREGON AGRICULTURAL 
COLLEGE 
In an interesting article on this subject in the May issue 
of Better Fruit Prof. C. I. Lewis of Corvallis says that in 
the work at the college it has been observed that very little 
pollen of either the apple or pear is transferred by air 
currents. The bee is the chief agent in pollenation. So 
great a factor is bright color in attracting bees, that in one 
case where the petals were removed from fifteen hundred 
blossoms, only five apples set. Professor Lewis, as a result 
of several years’ study of the self-sterility question affecting 
apples in the state of Oregon, gives the following list of the 
self-fertile, partially self-fertile, and sterile varieties in 
that state: 
Self-fertile. Baldwin, Bailey’s Sweet, Bethlemite, Col- 
vert, Fallwine, Grimes’ Golden, Keswick Codling, Long¬ 
fellow, Oldenberg (Dutchess of). Pumpkin Russett, Scott’s 
Winter, Shiwassee, Washington, White Pippin, Yellow 
Newtown. 
Partially self-fertile. Ben Davis, Canada Red, Fall 
Jenneting, Jewett’s Red, Mann, Pryor’s Red, Rambo, Stark, 
Spitzenberg, Wagener, Willow Twig, Whitney’s Crab, 
Yellow Transparent. 
Sterile. Autumn Sweet, Arkansas .Black, Beitigheimer, 
Bellflower (yellow). Bottle Greening, Canada Sweet, 
Canada Reinette, Delaware, Domine, Dutch Mignonette, 
Ewalt, Early Strawberry, Fallawater, Grape Bearer, 
Gravenstein, Golden Sweet, Gano, Green Sweet, Hoover’s 
Red, Haas, Holland Pippin, Holland Beauty, Hydes Keeper, 
Handwell Souring, Jonathan, King of Tompkins County, 
Limber Twig, May, Melon Sweet, Munson’s Sweet, Maiden’s

ENGLISH WALNUTS IN AMERICA 
In recent numbers of The Country Gentleman, Mr. D. N. 
Pomeroy of Lockport, New York, gives some interesting 
statements regarding the English walnut as cultivated in 
this country. It can be cultivated in the North, he says, 
wherever the butternut and black walnut grow. He states 
that while few of these nuts are grown as yet in the East, 
their quality is better than that of the Pacific Coast product, 
and they bring higher prices. The special grade quality 
can be sold at twenty cents a pound wholesale. One man 
has sold nuts at eighteen cents a pound to the amount of 
$360 an acre. Mr. Pomeroy says, “I know of no better 
business investment in agricultural or horticultural lines, 
and once established, a well-cared for grove is the best 
heritage a parent can leave to his family.” Can it be, then, 
that the growing of the English walnut is to be for the North 
what pecan culture in the South is said to be, the most 
“promising field in American horticulture . . . for 
sections that are adapted to this nut?” 
MISSOURI FRUIT CROP REPORT 
The State Board of Horticulture is in receipt of special reports 
from practically every county in the state, and from these advices tha 
following summary of eonditions regarding the fruit crop up to 
May 10 is compiled. 
Apples. On the whole, there promises to be a good crop of 
this fruit throughout the entire state. In the parts of the state 
where orchards bore heavily last season, there was not a heavy 
bloom this year. Also, there is universal complaint of a light bloom 
with the Ben Davis type, and now and then a few other varieties. 
Jonathan promises especially well almost everywhere. Reports 
seem to show the best yield in the northeast counties. In the 
southwest, the crop is well distributed, although not particularly 
heavy. It is believed there is enough bloom everywhere to insure 
as much fruit as the trees should be permitted to bear. Prospects 
now are for the largest crop in years. 
PkACHES. The best prospect for Elberta, the leading com¬ 
mercial peach, is in the northeast counties, but there are no large 
orchards there. This variety was frozen out in the northwest part 
of the state during the winter. In the eastern counties, peaches 
will be scarce except a few very hardy varieties which escaped injury 
in March and May. In the central counties, the peach crop will be 
irregular. In three of the counties, a fair crop of Elberta is re¬ 
ported, but for the most part the yield will be from seedlings and a 
few other hardy sorts. In the southwest, but few Elbertas are left. 
In the south central counties, where the large peach orchards are 
located, there will be a light crop of Elbertas—probably not more 
than ten per cent. The damage was .done there by the freeze in 
March 
Strawberries. From every part of the state the reports say 
there will be from 75 to 100 per cent of a crop of strawberries. 
The cold of May ist nipped some of the earlier sorts, but did not 
affect the general yield very much, but the season will be a few 
days later than usual. 
Cherries promise unusually well all over the state. 
Pears seem to have suffered greatly from the last cold wave as 
this fruit is reported short from nearly all sections. However, 
there are many isolated estimates of a 50 per cent crop. 
Small Fruits other than strawberries, including blackberries, 
raspberries, gooseberries, currants and grapes, on the whole promise 
well. A good many correspondents report a scarcity of raspberries, 
and there was some little damage done to grapes by the May ist 
freeze. On the average, grapes will make one-half of a full crop all 
over the state.
