However not all the oxygen present in the atmosphere is used in the process of combus- tion, since combustion ceases when the concentration of oxygen in the air becomes low. This requires definite provision of draft to secure rapid and complete combustion unless the sulfur house is very leaky, in which case more sulfur must be used. In order to secure uniform distribu- tion of the sulfur dioxide the vents should be so located as to cause the current of air and fumes to pass over as much of the fruit as possible.
