Very respectfully,

COLON, April 13, 1905. Mr. JOHN F. WALLACE, Chief Engineer Isthmian Canal, Evening Star Building,

Washington, D. C. DEAR SIR: The character of the men who have recently been coming out from Washington are no improvement on those we have been getting heretofore—in fact, the conditions are a little more aggravating owing to the fact that they have been sending out some higher price men who are of no use to us whatever: I call your attention to the following instances :

One, Gradison, Culebra, supervisor of excavation, $175 per month, former experience, Government work in Tennessee. Claims to have had experience around steam shovels, but the work he has done since coming here would indicate that he knows nothing about it. He is of no use to us.

Penny, sent here as supervisor of pumps, at $175 per month. According to his statement he has had considerable experience on contract work, but he is evidently not the man we want here. He is not capable and hustling and getting work out of men.

Anthony, supervisor of tracks, at $175 per month. Has had no experience on track work at all.

I also understand from Mr. Ehle that several of the yardmasters who have recently arrived and are getting $140 and $150 per month, are of little or no value, but we have not as yet had opportunity to fully determine their ability.

In going through Culebra this morning I found that the labor situation, owing to delayed pay day, is quite serious. The men are doing little or nothing, and are attempting to work when they have been without food and are physically unable to do manual labor. One or two individual cases that came under my notice were really pitiable. In this connection I inclose you a clipping from the Panama Star and Herald of this date. Very truly, yours,

W. E. DAUCHY, Acting Chief Engineer.

PANAMA, April 17, 1905. Mr. John F. WALLACE, Chief Engineer Isthmian Canal Commission,

Washington, D. C. DEAR SIR : On Saturday, the 15th, I received your cable message in regard to turning over the contract laborers received from the Panama Railroad to Mr. Prescott. I am arranging to do this as soon at Mr. Prescott can arrange for quarters for the men.

This will relieve the difficulty of having to keep track of so many different rates of pay, but it will probably make us short of laborers for a time, as Mr. Prescott tells me he has very few men to release that are not contract men.

I have just returned from a trip to Culebra, and want to again call your attention to the kind of men that are being sent to us from Washington. Last week we received 8 foremen, at $100 per month each, who are practically of no service to us. These men have been employed in various capacities, but none of them upon railroad work.

One was foreman for a contractor upon general city work in Philadelphia ; another was a foreman having had charge of the erection of telegraph poles ; another was a foreman in a stone quarry; and still another one had charge of a lot of mules in Government service.

These men are not only of no service to us at all, but are a detriment to the work in two ways:

In the first place, the cost of their salaries increases the cost of the output; and in the next place, they retard the work in this way: They are put in charge of a gang of men and a certain reliance must of necessity be placed upon them, and as no satisfactory results are obtained from their service we not only lose the services of the foreman himself, but of the men that he has in charge.

We have tried to use these men as dump foremen and are still doing so, but it is very necessary that we have men for such positions that know something about tracks, as they not only have to look after the dumping of cars, but the continual throwing of track, and sometimes quite a little track surfacing.

We have not as yet received a single track foreman from the States, notwithstanding the fact that four months have elapsed since we stated our pressing necessities in that line; nor have we as yet received any track tools, requisi'tions for same having been in since last November.

I wish to state that we have now practically reached our limit of any expansion of the work at Culebra until we get a large number of track foremen.

The rains have now started at Culebra: 'It is going to be necessary for us to use all the track foremen that we have there at the present time in keeping the tracks already laid in serviceable condition.

In fact, we have not enough men for this purpose, particularly as these tracks have not been put in proper condition during the dry weather, owing to this same lack of foremen and lack of track tools.

The only track tools that we have received to apply upon our requisitions have been some hand cars and rubble cars, which have just arrived at Culebra.

Since we first stated our needs for track foremen and track tools, 850 men have been added to our forces, and since that time we have had no increase whatever in track foremen nor track tools, except the few that we obtained from the Panama Railroad about a month ago.

Since our request went in in December for additional foremen, 6 additional steam shovels have been put to work, and our train service has been increased to about three times what it was. The amount of track to be maintained has increased in the same proportion.

It has been necessary to use every available track foreman to lay the additional tracks necessary to expand our output to what it is at present, and practically no work has been done upon the maintenance work.

The rains have now started at Culebra. It rained very hard there Saturday and was raining again there to-day, and in order to keep things running on the present basis it is going to be necessary to put what foremen we have upon maintenance work, which will practically stop all new track laying. Very respectfully,

W. E. DAUCHY, Acting Chief Engineer.

PANAMA, April 17, 1905. Mr. JOHN F. WALLACE,

Chief Engineer Isthmian Canal Commission, Washington, D. C. DEAR SIR : Up to the night of the 15th instant, we had taken out at Culebra 75,848 cubic yards of material. I have expected to get out about 150,000 cubic yards this month, but as the present week is holy week, in which it is almost

mpossible to get any labor done in this country, and owing to the further fact that the governor has issued a proclamation making Thursday and Friday of this week both holidays, we have left but ten more working days in his month, including to-day, and probably but a small proportion of the force will work at all between now and Easter Sunday. Yours, truly,

W. E. DAUCHY, Acting Chief Engineer.
