For my own part, I have only been able to arrive at three isolated conclusions on the subject.

First, that mere cultivation of the Campagna, as shown by Prince Borghese's unsuccessful experiments, does not at any rate immediately affect the virulence of the miasma, or whatever the malaria may be.

Secondly, that the malaria can actually be built out, or, in other words, if the Campagna was covered with a stone pavement, the disease would disappear--a remedy obviously impracticable; and lastly, that though the existence of the malaria cannot be removed, as far I can see, yet that its evil effects might be immensely lessened by warm clothing, good food, and prompt medical aid at the commencement of the malady.

Whatever tends to improve the general condition of the Roman peasantry will put these remedies more and more within their reach, and will therefore tend to check the ravages of the malaria.

Thus, the inefficient and obstructive Government of the Vatican, which checks all material as well as all moral progress, increases indirectly the virulence of the fever-plague; but this, I think, is the most that can fairly be stated.
I trust that, considering the importance of the subject, this digression, unsatisfactory as it is, may be pardoned; and I now turn to the third curse, which eats up the wages of the working man at Rome--a curse even greater, I think, than the "festas" or the malaria--I mean, the universality of the middle-man system.
