Real artists never apologize for their work. And they certainly don't do so prior to a showing. But since the one who compiles all these images and comments for a streamside makes no personal claims, he feels entitled to apologize for the quickshot nature of the following images snapped in haste and quickly pasted to the cloud. So there.
What we see here is an overgrown garden where last year there was barely enough short grass to wither and die in a drought and heatwave. But this year we've already had more rain than the total for last year, so plants grow to waist-high, climbing over, winding around, and nearly hiding the few intentional plants we set out one year ago. The first picture of the little orchard would look different today: I spent the past two days mowing it down and then installing several hundred feet of black irrigation pipe. Now we merely set the timer up at the well and watch water drip out at a rate of one gallon per hour, slowly moistening the sandy soil around blackberries, peaches, apples, pears, plums, and figs. Had we built the irrigation system last year, perhaps we would not have lost three quarters of the blackberry plants. Those few that did survive the record dry heat are now producing green fruits.
Last year we saw hardly any patches of widow's tears, but this spring they crowd every shady spot there is. The trail leading up Whitman's Rough to Priest's Cave is an overgrown mini-jungle of these sweet blue flowers and their thick-leaved grass-like parts. Occasionally a white flower among them can be found.
The prophet in me wants to warn of great swarms of grasshoppers for this summer. The situation is ripe.

Garden insect is jump champion
By Jonathan Amos BBC News Online
Move over the flea - the best jumper in the animal world is the froghopper.
This unassuming six-millimetre-long bug which leaves "cuckoo spit" on garden foliage can spring 70 centimetres into the air.Although the flea can do something similar, the froghopper is 60 times heavier.
"That makes froghoppers the true champions," said Professor Malcolm Burrows, head of zoology at Cambridge University, UK.
"It's not so much that they jump a little higher than fleas; it's the fact that because they're heavier, their jump performance is more impressive," he told BBC News Online.
Professor Burrows reports his investigation of insect jumping in the journal Nature.
Super acceleration
The froghopper ( Philaenus spumarius ) is well distributed across the world. It lives by sucking the juice out of plants. The developing young will hide from predators inside a froth blown out of their back ends earning the insects the nickname spittlebug.

Adults leap from plant to plant. They have long been known to be good jumpers but Professor Burrows has now measured their performance.The froghopper's secret is found in two hind legs that are so specialised to the high jump task that they are simply dragged along the ground when the insect is walking.
When the bug needs to leap, the legs form part of a very powerful catapult system. The limbs are lifted in a cocked position, held by ridges on the legs.
Two huge muscles, one controlling each leg, are contracted, and when they build up sufficient force, the legs break the lock and the insect springs forward.
"The legs snap open and all the force is applied at once," said Professor Burrows. "It accelerates in a millisecond up to a take-off velocity of four metres per second. That's phenomenal."
The scientist calculated the initial acceleration to be 4,000 metres per second per second.
Brain input
The G-force generated was more than 400 gravities in the best jumps monitored. In comparison, a human astronaut going into orbit on a rocket may experience no more than about 5 gravities.
We have always been led to believe that fleas are the jump champions of the animal world but Professor Burrows believes the record books should now be rewritten.
"The legitimate comparison is to look at how much force per body weight each animal can generate," he explained."A froghopper can exert more than 400 times its body weight; a flea can do 135 times its body weight; a grasshopper can do about eight times; and we can do about two to three times our body weight."

Professor Burrows studied the insect's athleticism as part of his research into how animals' nervous systems control body movement.
Insects are used in this type of study because their fewer brains cells are often larger than in more complex organisms, making it easier for scientists to see the processes involved.
