lie between the plots treated with a certain fungicide; that is, a
plot treated with Bordeaux mixture would be followed by a
check, and the check followed by another plot treated with Bor-
deaux mixture, this plot to be followed by another fungicide,
Am. Cu. Co., for instance, then followed by a check, and so on.
The spraying was done on June 1st and 2nd.
 It was impossible to visit the field again until June 28th,
when notes were taken carefully. The results are shown in the
following summaries:
 As before stated, the notes show that 62 per cent. of the
plants in the field, when the experiment commenced, were blight-
ed. The disease was quite generally distributed. No plot was
very much worse than any other.
 June 28-The plots left as checks showed an average in-
creaFe of blight of 13- per cent. That id to say, 6 per cent. of
the plants were blighted on June 1st, and on June 28th, 191
per cent. of the untreated plants were blighted.
 The first fungicide used was Bdx. Mx. No. 2.* Two plots
were sprayed. In the first, the vines below the fruit and the
ground about the plants to the distance of about six inches on all
sides of the plants were sprayed thoroughly, using about a pint
to each large plant. The plot was sprayed on June 1st, 1893.
On June 28th, as stated above, the field was again visited.
 The notes show that there was 4 per cent. increase of
blighted plants. This shows that a single spraying of the stems
saved 9 1-6 per cent. of the total number of plants thus treated.
Further, the frequent rains and warm weather made this the
most advantageous time for the fungus to thrive.
 Adjoining the check was a plot sprayed with the same mix-
ture made at the same time. This plot was treated in the usual
way, i. e. the mixture was sprayed over the foliage with no atten-
tion as to whether any reached the vines or not. Most of the
 *Bordeau Mixture is made by dissolving 4 Ibs. of quick (not air slacked) lime in a
small quantity of water. When thoroughly slacked, add enough water to make a good
whitewash. Dissolve 6 lbs. copper sulphate (blue stone) in ten or twelve gallons of
water. Strain through a "feed bag" into a barrel that will hold about forty-five gal-
lons. Then strain the lime solution into this. If it does not pass through the bag
well, add water until it does. The object of the straining is to take out all bits of rock,
straws and other material that would clog the spray pump. Stir thoroughly and add
enough water to make forty-five gallons of the mixture. It will be noticed that this
mixture is just one-half the usual strength. Work conducted under the direction of
Prof. Galloway, chief Div. of Veg. Path. U. S. Dep. Agr., indicates that the above
formula is as good as the other, and the ccst of the material only one-half as much,
This is often spoken of as Bordeaux mixture No. 2.
