Spray your garden's vulnerable plants regularly with a commercial or homemade deer repellent. These repellents typically contain components like sulfur, ammonia salts and capsaicin which deer find unpleasant. Even the store-bought varieties are concocted with natural ingredients and don't make use of harsh chemicals that might damage your plants' growth. Simply mist your garden every couple of days. If you're not inclined to shell out the money for a commercial repellent, try mixing up your own with eggs, garlic, ammonia, and/or hot sauce blended with water. Be careful about using repellents on crops you plan to harvest and eat yourself. Compounds like capsaicin aren't dangerous, but may influence the taste of edible plants. Deer are notoriously skittish creatures and are quite easy to scare off with the right stimulus. One particularly effective strategy is to put in a couple motion-activated sprinkler posts at the far ends of your garden or wherever deer tend to sneak in. When they get close, they'll suddenly be doused with a unexpected jet of water from the sprinkler, which will send them running. Installing a motion-activated sprinkler system is a pricier option, but one that is guaranteed to have repeated success. Along with its deterrent benefits, a sprinkler is also a convenient way of making sure your garden or yard is getting enough water. Loud, spontaneous noises are a surefire way to get rid of inquisitive deer. Whether it's an electronic noisemaker on a timer, a set of jarring wind chimes or a simple well-timed clap of your hands, a deer won't take any chances with what's generating the noise. Even leaving the back door open to let the sounds of household activity escape can be enough to dissuade a deer from coming any closer. Electronic noisemakers can be programmed to emit regular tones that will scare away deer but won't disturb the neighbors. Try fashioning a set of non-harmonic wind chimes from aluminum cans or hollow wood cuttings. Deer often travel in herds at night to forage, mate and play. That means that they might stumble upon the scrumptious treats in your garden in the small hours when no one is around to ward them off. Fortunately, mounting an automatic flood light on the outside of your house or some other structure near your garden can do the job for you while you sleep. When the deer begin to creep up to that squash vine or begonia bush, the flood light will activate and the intruders will run for cover. Most flood lights work at a particular range and angle. When installing a flood light, make sure it's properly calibrated to come on when movement is detected in the area of your at-risk plants.

Hold the clinometer so the curved rim of the protractor is facing downward. Tilt the clinometer until you can look through the straw or paper tube and see the top of a tall object you want to measure, such as a building. You can use this method to measure the angle between you and the top of that object, or the object's height. Keep the clinometer steady in that position, until the dangling string becomes still. Calculate the angle between the midpoint of the protractor (90), and the point where the string crosses the rim by subtracting one from the other. For example, if the string crosses the rim at 60, the angle of elevation between you and the top of the object is 9060=30. If the string crosses the rim at 150, the angle of elevation is 150-90=60. The angle of elevation will always be less than 90 since 90 is straight up in the sky. The answer will always be positive (greater than 0). If you subtract the larger number from the smaller and get a negative number, just cross out the minus sign to get the right answer. For example, if you calculate that 60-90=-30, the actual angle of elevation is +30. The tangent of an angle is defined as the side of a right triangle opposite the angle, divided by the side adjacent to the angle. In this case, the triangle is formed by three points: you, the base of the object, and the top of the object. The "opposite" side from this angle is the height of the object, and the adjacent side is the distance between you and the object's base. You can use a scientific or graphing calculator, an online tangent calculator, or a chart listing tangents for various angles. To calculate the tangent on a calculator, press TAN and enter the angle you found. If the answer is below 0 or above 1, set your calculator to degrees instead of radians and try again. If you want to find out how tall the object is, you'll need to know how far away you are from its base. Measure using a tape measure. If you don't have one, count the number of ordinary steps it takes to get to the object, then measure the length of one step once you find a ruler. The total distance is the length of one step multiplied by the number of steps you took. Some protractors have rulers marked along the straight edge. Remember, the tangent of your angle is (object's height) / (distance between you and the object). Multiply the tangent by the distance you measured, and you'll be left with just the object's height! For example, if the angle of elevation was 35, and your distance from the object was 45 units, the object's height equals 45 x tangent(35), or 31.5 units. Add your own height at eye level to your answer, since that's how far your clinometer was above the ground.
