OF FRUIT AND FOREST TREES. 201 



ed or injured part, will infallibly prevent the bleeding of trees, 

 or the oozing of juices through the wounds ot limbs or branches 

 that have been cut off in the middle of summer, when they are 

 in their highest vigour, and most rapid flow of vegetation ; by 

 which means, any wasteful discharge of the juices is prevented, 

 and they are dulv confined to their natural operations of giving 

 nourishment, growth, and fertility, to then' respective bodies. 



By employing the proposed remedy, trees of all kinds, 

 whether in gardens or orchards, in parks or forests, may with 

 greater safety and advantage be pruned or lopped in the spring, 

 or early in the summer, than in the winter season ; as the com- 

 position, when properly a.pplied, repels the flow of the juices 

 through the wound, causes a more active vegetation, and as- 

 sists nature more powerfully in healing the wound at the time 

 the sap is in full vigour, than when it is on the decline, as in 

 autumn and winter. 



It is also necessary to remark, that both fruit and forest- 

 trees (particularlv those which grow in the shade) are very lia- 

 ble to be affected with disorders proceeding from the growth of 

 liver-wort, and various kinds of moss, that adhere to the outer 

 bark of the tree, and frequently gain a considerable thickness, 

 that not only prevents the natural flow of the juices, but causes 

 a stagnation in the circulation, and brings on decay ; which, af- 

 ter destroying the outer bark, penetrates, by degrees, deeper 

 into the wood. Where this circumstance is observed, care 

 should be taken to clear the whole bark of the tree from these 

 growths; and where it is infected, to scrape or pare it away. 

 When the body of the tree is thus cleansed from infection, the 

 composition should be applied in a liquid state, to the parts so 

 cleaned, to close the pores of the wood; when the tree will soon 

 acquire a fresh bark, with improved health and vegetation. I 

 am confirmed in these opinions by the many experiments and 

 various trials that I have made to ascertain, by the most posi- 

 tive proofs, the properties of this composition, before I ven- 

 tured to offer it to the public attention. Indeed, every year's 

 experience has increased my conviction of its general utility, 

 when properly applied to the purposes for which it is recom- 

 mended. To give a more complete illustration of its virtues, 

 and to place the advantages arising from it in a stronger light, 

 I shall beg leave to state a few of the very numerous experi- 

 ments that I have made on the forest-trees in his Majesty's 

 gardens at Kensington, where the salutary effects of the com- 

 position are evident to every attentive observer. 



The first trials of its efficacv were made on some very large 

 •and antient elms, many of which were in a most decayed state.
