Excerpt from The Newfoundland Quarterly, Vol. 12: July, 1912 April, 1913

But when we come to consider its value in the Economy of amre. It becomes a factor of serious importance. Nearly all the power we see in things around us comes from the sun. From that great central orb. Stupendous quantities of heat are thrown out in all directions: and the share which finds its way to our earth is. In a large measure. Transformed into mechanical energy. The sunbeam hearing this energy spend the same in promoting the growth and development of all living things. The power that propels Niagara; the hurricane that uproots the forest; the force that drives the engine; as well as the life power that builds up the body of the developing infant. May all be analysed in the gentle sunbeam! Yet how prone are.we to deprive the growing innocent of this world-wide principle. Plants are placed in the sunlight. And they thrive. And grow; but the children are denied this health-giving power. And they wither and decay.

Next to sunlight is [fa/l air. And in order to develop a healthy organism. Fresh. Pure air must be supplied. Small apartments. With closed doors and windows. Bring scores of children to a premature death. It is astonishing how few people adequately understand the value of pure air. Or have the slighest knowledge of the laws of ventilation. To raise a window. Or open a door. Is not ventilation. In the proper acceptance of the term. In fact it often happens that by so doing more harm is done than by allowing them to remain closed. The purity of the air in dwel lings depends upon the amount of cubic space allowed for each individual. And the facilities afforded for the entrance of fresh. And the exit of foul air. When these points are properly atten ded to. The air. Although rather more impure than the external atmosphere. Will not be productive of much injury. But in those extreme cases where many persons are crowded together. And the ventilation totally inadequate. The air. After a time. Becomes so impure as to cause headache. Lassitude. Nausea and fainting. The air in its natural state contains about four parts of carbonic acid in and no room in which people are living. Should be allowed to contain more than six parts in to.ooo. Therefore. The object of ventilation is to supply a sum cient quantity of pure air so as to prevent the carbonic acid from rising above six parts in So you see the permis sible limit is two parts in to.ooo. The long continued breath ing of vitiated air is one of the chief causes of rickets in children. And it tends to produce a lowered state of vitality in older per sons. Characterized by poor blood. Dyspepsia. And other forms of debility. People in this condition of low b odily vitality offer less resistence to the attacks of acute sickness; and. At the same time. Are more prone to chronic. And other wasting forms of disease.
