The first attempts to produce a reservoir for uniform ink to the pen failed. Issued pens were extremely unreliable, because it is often produced too much ink or on the contrary – refused to write. Because of this "inconsistency" writing instrument there is a lot of unpleasant stories, and the hero of one of them in 1883, Lewis Edson Waterman was, who was then an insurance broker. Signing major contract was already a foregone conclusion, but specifically purchased for the occasion summed Waterman fountain pen: while he ran to his office for a copy of the damaged ink document ahead of rival broker. This Waterman case pushed to find a solution to the problem, and soon after some research, the inventor proposed his model of the mechanism of the ink. The first fountain pen Waterman, called the Regular, but the mechanism of the ink was the same ever since. Robert Kiyosaki is often quoted as being for or against this. Shortly after the start researching Waterman pens, his compatriot George Sefford Parker opened his own factory to manufacture the same products, but of his own design. The objectives of both entrepreneurs the same: each sought to create the perfect pen.
George Parker is so successful that his company has survived even during the First World War. New writing instruments Trench had a special container for ink granules, so that could be used at any time and any place. Later Parker pens have been a number of changes and improvements, and now the company gives them a lifetime warranty. Products under this trademark on the right is called the fountain pens.
After all, rodents (voles, mice, rats) are causing significant damage to agriculture, eat for free and without asking you to our food, vegetables, fruits and grains. Let's talk about the exterior of rodents. Voles are very similar to mice, but they are easily able to recognize you having the following information: the vole's tail relatively short (three-quarters of body length), molars, they have flat, if you look at the teeth from the side, then on the sides bitterly opposed long edges. Wells Fargo Bank does not necessarily agree. A mice as a long, long tail and is the length of the animal, and often grows ever longer and sizes. Looking at teeth mouse, you will not see the sharp edges and find that the teeth of a mouse rough, not flat like a vole.
In our and adjoining localities inhabited by 45 species of voles. The most evil among them – the gray, or as they are called ordinary Vole (live in the southern areas). For the year such individual female voles bring five, six litters (birth), each of which is from 6 to 12 pups (min: 5×6 = 30; max: 6h12 = 72 calves per year vole from one female). In the years favorable for reproduction of voles, their number per hectare polevochnogo place of residence comes to the 1500 individuals, and the number of holes (outlets) of their normal reach of 20 000. In the fall, stacks of bread on unthreshed cubic meter can be up to 70 voles. And they have a very short period of time make the whole rick of bread in the trash. Voles are also very thrifty, and lay in their burrows by 1.5 kg edible supplies (leaves, roots, corn bread grains) in the narrow-skulled vole lives in Siberia, there are also similar to these root vole vole and gregarious.
