Q: These are the most critical blocks in your wall. If they aren't level or adequately support the top half of your retaining wall, the whole project is going to look less than professional. Make sure that the foundational blocks are leveled off, sturdy, and tightly packed together. Add gravel or crushed rock to level the stone, if necessary. Add the first block to the trench, using a cornerstone. Make sure it is level from front to back and side to side.  Alternately, if there's no edge to the wall that is more visible than another, start at the edge that will be closest to another structure (usually a house). If you're building a straight or rectangular retaining wall, make sure that the backs of the blocks line up with one another perfectly; if you're building a curved retaining wall, make sure that the fronts of the blocks line up with one another perfectly. Some contractors prefer cutting off the top tongue or groove from the base stones before laying them down. Check for sturdiness yourself and knock the tongue off the block with a hammer and chisel, if necessary. Understand that curved retaining walls with tongues may not benefit from the interlocking grooves. These grooves will need to be cut off with a hammer and chisel if the layout of the pattern does not fit the direction of the grooves. This will complete the entire foundation. If you took the time to level off the bed, laying the first row should be easy. Use coarse sand where necessary to get a level finish on your foundation. Hammer the blocks down with your rubber mallet. Simply mark them at the appropriate length and cut with a mason's saw. Always use proper protection when cutting. This will provide excellent support, keeping your bottom layer from slipping back with time and erosion. This will prevent frost heave and keeps the soil from mixing with the backfill. Depending on how tall your retaining wall is, you may want to drape the filler along the back side of the trench or house, fill the trench with backfill until it's anchored the filter fabric down, and then drape the fabric flat out, on top of the backfill. This will free up any dirt or dust.
A: Begin by laying the foundation. Start at the most visible edge of the wall. Cut off the top tongue of the base stones, if necessary. Use coarse sand and a rubber mallet to level off the first layer of blocks. Cut individual blocks to complete the first layer, if necessary. Use crushed stone or gravel for backfill on your first layer of blocks. Place a filter fabric over the backfill. Sweep the first layer with a broom.

Article: Easier said than done! You may be able to determine the age based on clues in the design. Look for historical events or figures, or try to pick out words on the stamp. Exact years are not typically printed on stamps, so it can be quite difficult figure out exactly how old your stamp is.  Head to an expert stamp dealer if you need extra help. The older the stamp is, the more valuable it will be--so it’s worth the extra effort! Stamps printed within the last 70 years, even those in mint condition, probably won’t be valued any higher than they were originally. As with the stamp’s age, look for historical figures or events on the stamp, or words--knowing the language can help you narrow down the country. A picture of Queen Victoria, for example, is probably from 19th-early 20th century Great Britain, while a picture of the Hoover Dam may be mid-century American. Depending on your stamp, it might be easier to identify it before you try to determine the age and country of origin. After you’ve looked over the stamp’s physical condition, you’ll know enough about it to be able to find it in a reference book.  American stamp collectors often use the Scott Specialized Catalogue (now available in an e-book format as well), while British philatelists tend to use the Stanley Gibbons catalogue. Check out your local library to see what options you have. You can try looking at online resources and catalogues as well, but do so with a grain of salt. They may not be as accredited or accurate as reference books. The stamp’s rarity will depend on its age and quantity in its initial print run. The rarer the stamp, the higher the value; some stamp collectors even say that rarity is the single most important factor in determining stamp value, more than condition or age. Check in reference books or with a professional dealer to figure out the initial print run of your stamp. An old stamp won’t necessarily be rare and valuable. The 1861 1-cent Benjamin Franklin stamps, for example, aren’t very valuable because about 150 million of them were produced. Though in general you want your stamp to be as perfect as possible, error stamps are an exception. These rare stamps have an error in the design rather than the centering, perforations, etc. Error stamps are extremely valuable because of their scarcity; there may only be 50 or 100 of them in existence. Valuable stamp errors include design errors, such as a map showing the wrong border; an omission error, such as Thatcher Ferry bridge stamps in which the bridge itself was missing in the design; or an inversion, like the American Inverted Jenny stamps, which printed a biplane upside down.
Question: What is a summary of what this article is about?
Figure out the age of the stamp. Determine the stamp’s country of origin. Identify the stamp with a reference book. Determine the rarity of the stamp. Keep an eye out for error stamps.
