Most flies have mouthparts that are best described as two sponge pads and a straw. Their lips have grooved channels that allow liquid to flow in from the two fleshy pads attached to the fly's lower lip (the labella). Since they cannot chew, flies have to dissolve solid food into liquid, or at least into particles measuring 0.45 millimeters or less. To do this, the fly regurgitates saliva from its stomach, which dissolves the food until it is digestible. The house fly then uses its proboscis to suck up the liquefied food.
Though they eat with their mouths, house flies taste with their feet. This is why they are always crawling on your food. Since they also "taste" spoiled meat and feces, the last place you want them crawling is on food you're about to put in your mouth – not to mention flies constantly defecate.

Humus: The decaying dead matters in soil are called humus. Humus makes the soil fertile and provides nutrients to the plants.
Clayey Sol: Particles of clayey soil are very small in size. This makes the particles of clayey soil packed tightly. There is very little space among the particles. Water does not drain quickly through clayey soil because of less space among particles. So, clayey soil is not well aerated and retains more water.
Clayey soil is used in making of toys. Clayey soil is good for growing paddy.
Loamy Soil: Particles of loamy soil are smaller than sand and larger than clay. Loamy soil is the mixture of sandy soil, clayey soil and silt. Silt is the deposit in river beds.
Percolation Rate of Water: Amount of water drained through water in unit time is known as percolation rate of water in soil.
Moisture present in soil: Amount of water present in soil is called moisture present in soil. The amount of moisture present in clayey soil is highest and that in sandy soil is lowest.
Sandy soil: Sandy soil is not fit for any crop as it does not retain water. However, some thorns and bushes do grow on sandy soil. Millets can be grown on sandy soil.

After the death of his father in a battle in 1179, Prithviraj Chauhan succeeded the throne. He ruled over the twin capitals of Ajmer and Delhi which he had received from his maternal grandfather, Arkpal or Anangpal III of the Tomara dynasty.
The word Chauhan is the vernacular form of the Sanskrit term Chahamana. Several Chauhan inscriptions name a legendary hero called Chahamana as their ancestor, but none of them state the period in which he lived.
The earliest extant inscription that describes the origin of the Chauhans is the 1119 CE Sevadi inscription of Ratnapala, a ruler of the Naddula Chahamana dynasty. According to this inscription, the ancestor of the Chahamanas was born from the eye of Indra.
The 1170 CE Bijolia rock inscription of the Shakambhari Chahamana king Someshvara states that his ancestor Samantaraja was born at Ahichchhatrapura (possibly modern Nagaur in the gotra of sage Vatsa. The 1262 CE Sundha hill inscription of the Jalor Chahamana king Chachiga-deva states that the dynasty's ancestor Chahamana was "a source of joy" to the Vatsa. The 1320 Mount Abu (Achaleshwar temple) inscription of the Deora Chauhan ruler Lumbha states that Vatsa created the Chahamanas as a new lineage of warriors, after the solar dynasty and the lunar dynasty had ceased to exist.
The Ajmer inscription of the Shakambhari Chahamana ruler Vigraharaja IV (c. 1150–64 CE) claims that Chahamana belonged to the solar dynasty, descending from Ikshavaku and Rama. The 12th-century Prithviraja Vijaya mahakavya, composed by Prithviraja III's court poet Jayanaka, also claims a solar dynasty origin for the ruling dynasty. According to this text, Chahamana came to earth from Arkamandal (the orbit of the sun).
