"Inquirer," Burlington, Kansas. So far as known the buds of plants burst into leaf solely from the action of heat on the buds, and the temperature of the earth has nothing whatever to do with the act of foliation. Root action, so far as we know, has to do solely with nutrition, - and we believe has nothing whatever to do with the development of foliage.

"Zero" says: "Pardon my doubts, but I find nothing in my text books that confirms your answer to " Inquirer," in regard to the action of roots in aiding leaf development. I should be much obliged if you will give references to authorities for this view".

[We are glad to find a disposition to look into matters of this kind. It is too much the habit to take things on trust. In this case we did not know that "authorities" failed to confirm our view, - but we suppose they must have thought it needless to refer to it, for the truth is apparent to every practical gardener. For instance, a grape vine may have two branches, - one shall be led into a forcing house, the other kept in a cool vinery; the roots remaining in the same border and under the same circumstances in both cases. The hothouse branch will grow and bear fruit, while the other remains dormant till the temperature rises. Again you may cut down a willow log, and if it remains exposed to the summer temperature it will sprout out into leaves and branches, without any roots at all. These are a few illustrations out of a large number, which might be given, and while we commend the effort of " Zero" to look into his books for authorities, may suggest at the same time that he look a little into the "book of Nature " open all round him. They are both good teachers. - Ed. G.

It became necessary to raise a fund of $60,000 to keep things up to the best, and at the date of this writing one-third of the amount has been contributed by the public spirited citizens of Boston who seem never behind-hand with the means when science is to be advanced.
