Writing to Land and Water, Mr. Higford Burr, Aldermaston Court, Reading, says:
" I dare say that most of your readers who take any interest in planting have often remarked how an Oak or other tree of fortuitous planting has attained a fair growth, owing to the protection of a Thorn bush, which has saved it from cattle. Taking a hint from Nature, I desired my woodman last Autumn to plant in my park, by way of experiment, a dozen trees, about six feet high, in such a manner that they would be protected each by a Thorn. He performed his task with great judgment, and I am happy to say that hitherto the experiment appears to be so successful that I shall repeat it on a larger scale this next November. Planters, of course, will see that my object is to plant single or grouped trees, without having to incur the expense and trouble of fencing them; and having been thus far successful, I am desirous of imparting this 'dodge' to others, who, having rough grounds, may thus make use of their Thorns as nurses for more valuable trees".
In America we cannot wait for the Thorn trees to grow, but cut the Thorn's branches and work them round the trunks to be protected. Around Philadelphia it is not uncommon to see Honey Locust, Yellow Locust, Osage Orange and even Blackberry branches used as protectors in this way.
