Flying the flag at half-staff means flying it halfway up the flagpole. You should fly the flag at half-staff on Memorial Day and whenever the president or your state governor declares a period of mourning. Do the same when you go to lower the flag from half-staff at the end of the day. If there are any other flags around, they should be raised after the American flag and lowered before it so the American flag is flown the longest. Always be prepared to grab the flag with your hands when it reaches the bottom of the pole.

One-sentence summary -- Fly the flag at half-staff on special occasions. Raise the flag to the peak of the staff first before flying it at half-staff. Raise the American flag first and lower it last. Never let the flag touch the ground when it’s being lowered.

Q: Start learning your fingerings and playing scales to develop the fundamentals to start playing music. Scales might not be the most exciting thing to learn when you're first getting started, but before you know it you'll be able to hit all the right ones to play the "Imperial March" from Star Wars (the "Stairway to Heaven" of the tuba) and take off from there. The tuba is both a rhythmic and a melodic instrument, providing the big, sturdy, bottom line of the band. To be the best tuba player you can be, it's important to practice playing rhythmically, so you play not only the right notes, but the right notes at the right time. Great tuba players are as rhythmically precise as a drummer and as melodically clear as a trumpet player.  Practice with a metronome. Even when you're playing scales, play them in time. When you're playing your practice songs, play them in time. Learn to internalize that sense of time by tapping your feet and paying close attention to your rhythmic motion. Practice your counting. Sometimes, tuba notes will be spaced out very far, meaning that you'll mostly be counting empty measures on some songs. Develop a good method for counting rests to make sure you're always on time for your big notes. Tuba is a much better instrument when you play it with others. Sometimes, the sheet music for a song on tuba involves only a few notes (the bass line), which you can learn quickly and get bored with just as fast. But when you add the trumpets and the trombones, the flutes and the clarinets, those few notes become so much more. You're making music. Consider taking private lessons as well. Like most instruments, learning a tuba properly usually requires in-person instruction. Whether you receive that in school band or in private lessons, getting one-on-one instruction is a good way of keeping you from building bad habits and moving forward with your playing. Explore good instructors available in your area and sign up. These slightly more advanced techniques are useful for playing fast passages, when you're called for. While this isn't something that you need to start learning when you're first getting to know your way around the tuba, developing the clarity, tone, and speed of your notes can be helped with learning to tongue quickly.  When double tonguing, think either ta-ka-ta-ka or da-ga-da-ga. Try saying it first, and when you try double tonguing, think as if your tongue is moving in one of the two ways described above. Triple tonguing has four approaches: Ta-ta-ka, ta-ka-ta, da-da-ga, or da-ga-da. Try all, and choose the one that works best on you and stick with it. A tuba isn't as delicate as say, a violin, but it is still quite prone to denting and scratching. Always transport your instrument in a case and learn to maintain your tuba to get the best possible sound.  Empty the water that is in your tuba frequently by pushing the water key and blowing air into the instrument without vibrating your lips. Check individual valves by pressing down each one in turn and blowing; if there's any water in the tubing, it should sound and feel obvious. You may need to remove the tubing or rotate the tuba to clear everything. Find somewhere for tuba repairs. Professional instrument repairmen might charge you a pretty penny for fixing things, but they know what they're doing and it's better than ruining a giant investment by messing with something you don't understand.
A: Practice scales. Practice your timing. Join the school band or a community orchestra. Learn double and triple tonguing. Care for your tuba properly.

Article: Gray tree frogs thrive in high humidity levels, so it’s important that you keep your frog’s aquarium humid by lightly misting it with water once a day. You should also lightly mist your gray tree frog with water since gray tree frogs stay hydrated by absorbing water through their skin. To mist your frog and its tank, you can use a mist spray bottle filled with spring water or dechlorinated water. Regular cleanings will help prevent your frog from getting sick. To clean out its aquarium, carefully transfer your frog to a separate container that it won’t be able to escape from. Then, replace the substrate at the bottom of the tank with fresh, clean substrate, and remove any uneaten insects and debris in the tank. Next, take out the perches and any fake plants and scrub and rinse them with water to clean them off. You should also replace the water in your frog’s soaking dish with fresh spring or dechlorinated water. Finally, wipe down the inside of the tank with paper towels. Avoid using any cleaners other than water since they’re not safe for gray tree frogs. Generally, it’s best to only handle your gray tree frog if absolutely necessary, like when you’re moving it to a separate container to clean its tank. When you do handle your frog, it’s important that you wash your hands first so you don’t transfer any oils or potentially toxic substances to your frog’s skin. You should also wash your hands after handling your frog since gray tree frogs secrete a toxin that can cause extreme discomfort if it makes contact with your eyes, mouth, or nose, as well as any cuts or abrasions you have. All captive amphibians are susceptible to health issues that can range from nutritional deficiencies to infectious diseases. Therefore, it’s important that you intervene immediately and bring your frog to see a vet if you think there’s something wrong with it. A vet should be able to determine what’s wrong with your frog and prescribe the right treatment plan. Some common warning signs that there might be something wrong with your frog that you should keep an eye out for include:  Inactivity Weight loss Bloating Blotchy skin Cloudy eyes Swelling
Question: What is a summary of what this article is about?
Mist your gray tree frog and its aquarium with water every day. Clean your frog’s aquarium once a week. Wash your hands before and after handling your frog. Take your frog to a vet if you notice signs of health problems.
