Many schools open now before Labor Day now. As is often the case, the change may be eminently practical, but downgrades the importance of an old marker of the passing year, the last long holiday weekend until Thanksgiving. The final weekend of freedom was bittersweet, with gloomy thoughts of the looming imprisonment brightened only by the prospect of having new clothes and tight new shoes to wear the first day of class (if one were a girl, anyway).
Two delightful picture books pay tribute to sand as superlative building material for summertime imaginative play—Israeli author/illustrator Einat Tsarfati’s Sandcastle (2018; American translation published by Candlewick Press, c.2020 in Sommerville, MA) and Peter Bentley’s Captain Jack and the Pirates illustrated by Helen Oxenbury (New York: Dial, 2016). In Tsarfati, a girl is the architect of a fantastic palace; in Bentley a trio of boys build a ship out of whatever they have at hand.
A redhead with a red shovel, green pail, and sun hat walks by the multitudes on towels baking at the beach, ignoring the picnickers, gamers, readers, mermaids, babies, witches, and snorkelers. She gives the shoreline a quick look, then kneels and gets to work. Her creation is at least four stories high and its roofline with multiple turrets, spires, and domes is a beachy Chambord with spectacular ocean views.
Any king or queen worth a crown (royal children in tow) flock to see the castle. (A few people on the beach sneak in too.) They dance the night away, refreshing themselves with unlimited dollops of ice cream, but in the morning, sand in their beds or breakfast pastries is not enchanting. Who can play cards on a table made of sand or compete in the Triathlon of Knights with sand in the seat of their armor? Well, what did they expect staying in a sandcastle? Luckily the unnamed heroine devises a solution. Everyone makes good firm sand balls and hurls them at the walls. When the sea rushes in through the holes, everyone has a grand time splashing in the water. Once the sandcastle has been washed away, she starts all over.
No castle for Jack, Zack, and Caspar. Born naval architects, they build an enormous galleon of sand and outfit it with mast (two sticks), a sail (shirt and bib), and cannons (three plastic buckets). Mainsail hoisted, the pirate Captain Jack and his crew sail off to find adventure and loot. 
In the misty distance a pirate ship looms and they set their course dead ahead, prepared to board and cover themselves with glory and pocket gold doubloons. The gnarly rival pirates are ready to give as good as they get when a tropical squall blows our intrepid three far off course. 
Their ship is swamped and it melts into the surf. Undaunted Jack, Zack, and Caspar sneak up on their enemy’s hideout and discover sugary booty on the wooden table inside. Ambushed by the crew members left behind to guard it (Mum and Dad), our buccaneers must submit to being rubbed with towels and changed into dry clothes. Luckily their captors know that the quickest way to the hearts of marooned pirates is an ice cream cone. 
Oxenbury fills out Bentley’s reassuringly familiar story line with clever details that creative little boys playing together could dream up themselves: it is magical while staying within the boundaries of the real world.
It is delightful how sand and ice cream go together like cookies and milk in these two picture books set in such different imaginative spaces. The storylines may be considered by some to be too gendered, but the virtuoso use of nice wet sand will surely appeal to any child who loves being by the water on a bright sunny day.
