The United States Government stands high in the estimation of the people of other nations, by the aid it gives to scientific explorations and investigations, and it is chiefly because of its interest in the development of the progressive paths of peace, while the rest of the world is mainly occupied with the arts of war, that population, capital and enterprise are so freely poured in upon us. Indeed, there is very little left for a United States Government to do but to look after the protection of the people from internal enemies since it has no foreign foes to menace them. And we have no greater foe than ignorance, - and especially that class of ignorance which only exact scientific knowledge can destroy.

This work of Prof. Riley and the Entomological Commission is one which will do much to maintain the excellent reputation of our government, to which we have already referred; and it will do much towards curbing the destructive power of one of our national enemies, - the cotton worm. Indeed, a study of this work will not be of value to the cotton raiser only, but will expand the view of all engaged in the war against noxious insects of many kinds. So far as the cotton worm is concerned, we have here given the history of the insect copiously illustrated in all its stages of growth, as also of others which have any possible relation or connection with it. Also all sorts of machines and contrivances by which the insect may be caught and destroyed. The wide diffusion of such knowledge as is contained here, cannot but be of untold value to the country in dollars and cents; for though the intelligent man generally gains what the ignorant one loses, it is always an absolute loss to any country where even one man's labor is thrown away.

How to Learn Short-Hand without a Teacher, we have from S. R. Wells & Co., New York.

The third bulletin of the United States Entomological Commission gives the results of Prof. Riley's researches on the cotton worm, which is so injurious to the cotton plant, that the average loss is estimated at over twelve millions of dollars a year. Sad enough, but there is a human species that wastes vastly more annually, by keeping millions of men under drill.. It would be better to try to exter-pate the latter worms than the former.

Contrary to Darwin's conclusions, that Dro-sera is carnivorous, Prof. Regel finds on comparing a number of plants fed with meat, with a series which were not, that while the average weight of the seeds was greater in the former case, this was more than compensated by their much smaller number, the gross weight being considerably less. And found also, that the leaves were obviously injured by the flestb food, and that the power of the plants to resist the Winter was diminished. He thinks the epithet carnivorous, improper.
