So far we feel highly gratified at the success which has
attended our efforts. I gravely doubt whether you would now find, in this
whole county, a single case of infection. But on the other hand, I could
not, of course, venture to state unqualifiedly that there may not be
certain isolated cases--"
"Pat! Do stop that growling! What ails you, anyway? I never saw him act
that way before. I wonder if he could possibly be--" She looked at
Sommers questioningly.
"Infected?" he finished for her understandingly. "As a matter of fact,
that may be possible, though I should not consider it altogether
probable. Since the period of incubation varies from three weeks to six
months, as in man, the dog may possibly have been infected before coming
into your possession. If that were true, you would have no means of
discovering the fact until he exhibits certain premonitory symptoms,
which may or may not form in themselves conclusive evidence of the
presence of the disease."
Helen May got up from the rock and moved away, eyeing Pat suspiciously.
Pat got up and followed her, keeping a watchful eye on Sommers.
