allowed to rot in the open air, or are burned, much of the valu-
able nitrogen will be lost (Md. B. 11, p. 69).
 From the foregoing it will be seen that more nitrogen and
potash are left in the field than are taken off, and about half as
much phosphoric acid. If we compare this with the stubble and
roots of cow-peas, it will be seen that the tomato vines on an acre
have 5 per cent. more nitrogen, two pounds more phosphoric acid
and twice as much potash. In fertilizing, more of the essential
elements are needed than the above figures show, because the
plants do not completely exhaust the soil in a single year. Then
the fertilizer is not all in an available form.
 The above amount of fertilizer in the vines is altogether of
too much value to be lightly dealt with. Another point in favor
of making use of the vines is that it adds the much needed
organic principle to our soil. It adds what so many people con-
tend is the most important part of muck-i. e., its presence aids
the plants in appropiating the needed foods.

 WHEN TO USE THE VINES.
 There is probably no other time when there is more of the
 organic matter present than just at the close of the shipping
 season. If now these vines be turned under, and a growth of
 beggar-weed be started, the ground would be covered with a
 heavy coat of vegetation during the hot summer months, and in
 the fall another coat of humus be ready. This should be turned
 under whenever it is best for the land. There are some lands that
 are not hurt but greatly benefitted by turning under a crop of
 green manure; we are told, however, that it is not only better
 but absolutely necessary that only dry, well-rotted vegetable mat-
 ter be plowed under, because, the green manure gives a sour-
 ness to the soil which it takes several years to overcome.

 DO WE FERTILIZE TOO HEAVILY?

 There has been much said about fertilizing tomatoes too
 heavily. *From all tests made in this line, indications are that
 there is little or no danger of fertilizing too heavily, but the
 danger lies in fertilizing improperly. The most vigorous
 vines I have seen in this State were some that received
 two pounds of fertilizer to the vine, besides a lot of trash." The
