Это было давно-давно, в незапамятные времена. тогда и звери, и птицы жили без всякой работы, ничего не делали, ни о чём не заботились. а от скуки да от безделья часто ссорились и дрались. и вот, чтобы положить конец всем раздорам, они решили заняться важной работой – вырыть большую реку, даугаву. одна лишь иволга, птица, накликающая дождь, не хотела копать реку. – для чего мне вода на земле? мне и небесной воды хватит! а звери и птицы не стали долго судить да рядить. тут же и принялись за работу. и работали не за страх, а за совесть. заяц впереди бежал, дорогу реке показывал. а ведь всем известно, что заяц прямо бегать не умеет, бежит-петляет. вот потому и даугава не прямая, а вся в извилинах получилась. лиса спешила за ним вслед и своим пушистым хвостом намечала берега даугавы. крот-землекоп прокладывал русло. барсук шёл за кротом, русло расширял. медведь, как самый главный силач –ведь недаром же он самый главный силач! – таскал из русла землю и сваливал в кучи. и сейчас видны на берегах даугавы изрядные горы и пригорки, которые медведь насыпал. да и все другие звери и птицы трудились что есть силы. и все ссоры были забыты. а когда вырыли даугаву, то собрались посмотреть, какова река у них получилась. да тут же и проверили, кто как работал. крот и медведь даже землю с себя стряхнуть не успели –так усердно они работали. – вы у нас самые трудолюбивые, – сказали им все звери и птицы, – поэтому можете с честью носить всегда свою рабочую одежду! с тех пор медведь и крот так и ходят в тёмных шубах. волку, который и лапами рыл, и клыками , оставили навсегда и лапы, и морду чёрными. пусть все знают, как хорошо волк работал. гуся и утку тоже хвалили за усердие. им разрешили и плавать и мыться в реке сколько захотят. а другим птицам, которые работали не так старательно, позволили только пить из реки. в это время иволга, накликающая дождь, по-прежнему прыгала и посвистывала среди ветвей. – у меня такой красивый жёлтый наряд, -оправдывалась она, – не могла же я в своей праздничной одежде делать эту грязную работу! тут звери и птицы рассердились на неё. – пусть иволга никогда не пьёт чистой воды ни из реки, ни из пруда. пусть утоляет жажду дождевой струёй или каплями росы, которые проступают на лбу лежащего камня! поэтому и приходится теперь иволге страдать от жажды. и когда другие птицы, предчувствуя грозу, умолкают, иволга кричит жалобно-прежалобно, кличет не накличется, просит дождя
The beardless sly man Aldar-Kose lived in one aul. His eyes were sharp, his legs were quick, his hands were agile, and his mind was even more agile. Aldar-Kose loved to joke and laugh, especially at fools and misers. He had no wealth, but by cunning he did not get himself a meal of fat ram.
Zhatyr-bai was a greedy and stupid person. His flocks were large: he would start counting at dawn, and finish at dusk. Once Aldar-Kose came to him and said:
- Honorable buy, I have two rubles, but no wallet. I walk, hold the money in my hand - my hand is tired. I want to get rid of this money. Will you help me?
- Come on, come on, I will help! - buy was delighted. - Just tell me how?
“Sell me some poor little goat for two rubles,” says Aldar-Kose.
Thought, thought buy: "Well, you can sell." He caught a lame goat in the herd, skinny, barely alive, which had only two days left to die, and gave to Aldar-Kose:
- Here, take it, although it's a pity to give it away cheaply. Good kid. Give me two rubles!
Aldar-Kose took a goat, and keeps money in his fist:
- You know what, honorable buy. I changed my mind. Take two rubles and a kid to boot, and give me a lamb.
“Well, not a bad exchange,” thought Bay, “two rubles and even a kid to boot!” - and went to catch the lamb. Caught the smallest and serves Aldar-Kose:
- Here, take it. Nice lamb. Give me two rubles and a kid.
Aldar-Kose took the lamb, but he holds the money in his fist and does not let go of the goat:
- You know what, honorable buy. I changed my mind. Take two rubles, a kid and a lamb to boot, and give me a goat.
"Not a bad exchange," thought Bay, "two rubles and a goat, and even a lamb to boot." And he went to catch a goat. He caught the thinnest one and serves to Aldar-Kose:
- Here, take it, good goat. Give me two rubles, a kid and a lamb.
- Wait, wait, respectable bay! - says Aldar-Kose. - I changed my mind. Take two rubles, a kid, a lamb and a goat in addition, and give me only one ram, but let me choose it myself.
“This exchange is more profitable than all the others! - thought the delighted buy. - Two rubles, a kid, a lamb and even a goat to boot - and all this for one ram! And he says to Aldar-Kose:
- Well, choose!
He chose Aldar-Kose for himself the biggest, fatty ram, gave the bai two rubles, a kid, a lamb and a goat in addition, put the ram on his shoulders and went, and bai Zhatyr-bai laughed, rubbing his hands:
- What a fool Aldar-Kose! He gave so much good for just one ram!
Bay did not understand which of them was the fool.
