We fully appreciate that in a highly fertile soil, wellmanaged, crops are less liable to disease and that they muchmore readily keep the mastery over weeds than they do ona poor soil or on one in bad condition, poorly managed. Itit equally true with the organs of the animal body; if theyare abundantly nourished, surrounded by congenial condi-tions, the possibilities for contracting tuberculosis, cholera,smallpox or other forms of contagious diseases whose germswe must remember are almost always about us, no matterhow careful we may be, are very much reduced. It is the Seinous Effects of Insufficient Ventilation. 27. body starving for want of oxygen or for want of any otheressential food material, or which is weakened in any otherway, which is most likely to be overpowered by one or an-other of these foreign organisms, and a single germ maygain the mastery over a system in weakened conditionwhere multitudes of them would be harmless within a vig-orous constitution, well nourished and normallv cared since the body out of which lifehas gone begins immediately to passinto decay it stands to reason thatone sick or weak must be more liableto suffer from attack than anotherwho is strong, and the truth of this isabundantly borne out by by those expressing therate of mortality resulting from con-tagious disease associated with condi-tions of inadequate ventilation.
