It really doesn't matter. The point is that by placing a border between your yard and where it meets the sidewalk or a neighbor's property, you have accomplished two things: First, it is clear that the yard is the product of intent and effort, not neglect; second, you solve the practical problems of large native plants flopping over into others' yards or obstructing drivers' and pedestrians' sight lines.

Nothing repulses more than arrogance. Don't be an arrogant natural landscaper. Don't be a self-righteous natural landscaper. Remember that you are a pioneer who is trying to win converts, not a martyr willing to go down in a flood of litigation and neighborhood disgust. Natural landscapers who consider themselves better than their neighbors serve only to undermine their own cause. If you tell your neighbors why you're tearing up the lawn, or planting native plants, or constructing a water garden, chances are that they will accept it.

There are two aspects of advertising: before and during. Educating your neighbors and local officials before you begin your natural landscape project is essential. Telling them what you're doing and why you're doing it, increases understanding and reduces apprehension. If you have the conviction to do the right thing, then you should have the conviction to tell others why you're doing it. Once planted, I suggest a sign. The first involved the presumed inhalation of virus particles in a bat cave, a second involved laboratory workers creating an aerosol and inhaling virus particles while using a power saw to cut the tops off skulls of rabies suspects, and thirdly, cornea transplants where the cornea donor had rabies.

These routes of infection are not considered of general importance. Animals with furious rabies exhibit aggressive signs early in the disease and then become paralyzed. Those with dumb rabies simply become paralyzed and die shortly thereafter. Animals with furious rabies usually have an excitation phase lasting several days. The animal is restless and soon becomes vicious, biting at anything and everything. This action gradually subsides; incoordination and tremors are often apparent.

Convulsions, paralysis, and prostration occur just prior to death. An important consideration in reaching a clinical diagnosis of rabies in animals, especially wild ones, is that no sign or series of signs is typical or characteristic.

Signs of other diseases such as distemper, hepatitis, listeriosis, tetanus, botulism and some parasitic diseases are similar to those of rabies. Encephalitic syndromes can also be caused by plant or chemical toxins. These clinical signs are so varied and overlapping that limited confidence should be placed on a clinical diagnosis of rabies. The only sure way to diagnose rabies is with laboratory tests.

There is no gross pathology evident in animals which have died of rabies. Microscopic lesions of the central nervous system are inflammatory and similar to those seen in other virus infections. Negri bodies inclusion bodies in the cytoplasm of neurons of infected animals are positive proof of rabies infection. In the event of a bite exposure, dogs and cats are quarantined for 10 days for observation. If no illness becomes apparent within that time, they are considered not to have rabies.

Wild animals that have bitten or exposed humans or unvaccinated domestic animals should be killed immediately, and their heads submitted to the proper health authorities as soon as possible. Bats should be sent in whole. Care must be taken when killing such animals to avoid damaging the brain. The individual handling the dead animal should wear rubber gloves as a precautionary measure.

Veterinarians and local health departments should have mailing containers to submit the head or body for testing. If none of these are available the specimen should be placed in several plastic bags, cooled, and driven to the Wildlife Disease Laboratory for handling.

At the Health and Human Services Rabies Laboratory, diagnosis is made by placing a small amount of brain tissue on a microscope slide and treating it with a fluorescent dye. When viewed under a microscope equipped with ultraviolet light, rabies-positive specimens will fluoresce, or glow.
