“When additional sets of blue-prints of the same set of drawings are imported, such additional sets of blue-prints are to be valued for duty at $5 per set, in addition to the value of the original drawings or first set of blue-prints imported in lieu thereof, as above.”
This schedule was canceled after the above date, for what reason we are unable to state. The duty now in force is practically nominal, being a charge upon the value of the paper only and the time spent in making copies, Such as blue-prints.
As an evidence of the unreasonableness of the present tariff and the hardship inflicted on Canadian architects, American architects may erect expensive buildings in Canada, having all the draughting done in the United States, whereas Canadian architects are practically debarred from carrying on work in the United States under any condition by reason of the duty and the alien-labor law.
We would suggest a tariff, as follows:
Each set of original drawings or single set of . copies or blue-prints of same, if brought into Canada as a substitute for the original drawings, 40 per cent, of the architect’s fee, the architect’s fee being at 2% per cent, on the estimated cost of the building, for working drawings and specifications. The same, if accompanied by full details, or for full details afterward furnished, 40 per cent, of an. additional fee of 1 per cent, on the estimated cost of the building.
When additional sets of copies or blueprints of the same set of drawings are imported, such additional sets of copies or blue-prints are to be valued for duty at $5 per set, in addition to the value of the original drawings, copies or blue-prints. A declaration to be taken that such sets are merely duplicates of drawings or copies or blue-prints already imported.

Merits of Loblolly or North Carolina Pine.—The Forest Service-has been conducting extensive tests at the E. P. Burton Lumber Company’s saw-mill, near Charleston, S. C., to determine the strength of loblolly pine. This timber, which is known on the local market as North Carolina pine, forms the greater part of the lumber cut at this mill. The loblolly pine furnishes a useful construction timber of moderate strength, is of very rapid growth, and reproduces readily. For these reasons it will remain one of the most important timber trees of the South. Correct data on its strength will be of permanent value.
It is found much more convenient to take the testing-machine to the mill instead of bringing the large sticks of timber to the laboratory from the mill. The conditions
to which the stick of timber is subjected after being cut in the forest determine to some degree how it will act when put in use where it will have to carry a load or bear a strain. And so it sometimes becomes an important matter to know the history of the sticks tested. The logs from which it is desired to cut the test-pieces can be selected in the forest, marked and subsequently identified at the log pond. A concise history of each log is kept, showing the location of the tree in the forest, the kind of soil in which it grew, the time the log lies in the water. On arriving at the mill the log is sawed in any way desired, arid can then either be tested shortly after coming from the saw or laid aside for the purpose of air-drying or kiln-drying before testing. Every step of importance in the life of the log after cutting is thus known, and many peculiarities which arise in the behavior of sticks when tested can be explained.
The plan of work at Charleston includes investigations to determine the effect of knots on the strength of timber; the relative strength of air-dried and kiln-dried timber; the effect of rate of growth upon the strength; the influence of the relative strength of sap and heart wood; and the influence on the strength of the method of sawing.—Charleston, S. C., News.
Tasmanian Blue Gum.—Experience at the Dover Harbor Works has demonstrated in a striking manner the remarkable physical properties of the Tasmanian blue gum (Eucalyptus globulus), which is probably the strongest and most durable timber in the world. It certainly is denser than any other wood, having the specific gravity of 1.2, and is practically impervious to the attack of the teredo. These facts have only been recognized by timber experts within the last few months, and it is well that they should be generally known. So far as the works at Dover are concerned, the chief value of the blue gum piles from a constructive standpoint was that, while Oregon pine piles could not be driven in deep water subject to strong currents unless weighted at the end with iron, the piles employed required no such assistance. Further, owing to their immunity from injury by the teredo and to the great strength of the timber, most of these piles have been in continuous use for more than four years, and some of them have been driven three or four times in different positions. We learn from Mr. W. Heyn, the timber expert of Messrs. S. Pearson & Sons, that tests very carefully made show that the Tasmanian wood wilL sustain about double the weight that can be carried by English oak, and will even regain its elasticity after having been subjected to loads equal to the breaking weight of oak.—The Builder.
